Bias in Health Studies
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.

asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.

of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it

Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).

The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.

This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.

Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.

This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?

“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.

Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.

representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.

happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.

interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).

linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.

A cool part of the session was learning about how to minimize bias:
Use random sampling to reduce selection bias.
Standardize data collection methods to cut down on information bias.
Use blinding to avoid observer bias.
Always look out for potential confounders and adjust for them statistically.
Reflection:
This topic honestly made me more skeptical—in a good way. I used to take research findings at
face value, but now I realize how studies can go wrong in so many sneaky ways. Bias isn't just a
“mistake”—it’s often built into the system. Understanding it makes me a better reader, a more
thoughtful critic, and eventually (hopefully) a better researcher. It’s like spotting illusions—you
can’t trust your eyes until you know the tricks.
Bias in health research isn’t just some abstract concept; it’s everywhere. And once you see it,
you can’t unsee it. Bias basically means there's a systematic error that pushes study results away
from the truth. It’s not just random noise—it distorts the whole picture.
We first talked about selection bias, which happens when the participants in a study aren’t
representative of the population. Like, if you only include hospital patients in a study about
asthma, you’re likely missing milder cases that never go to the hospital. So your results end up
biased toward more severe outcomes.
Then there's information bias, which happens when the data collected from participants is
inaccurate. For example, if someone lies on a survey about how much they smoke, and it
happens more in one group than another, that’s differential misclassification—a major source
of bias. It can either dilute or exaggerate associations.
We went over some types of information bias like:
Recall bias: common in retrospective studies; people with a disease might remember past
exposures more clearly (or even exaggerate them).
Observer bias: when the researcher’s expectations influence how data is collected or
interpreted.
Reporting bias: when certain results are more likely to be reported than others (looking
at you, pharmaceutical trials).
Another key form of bias we explored is confounding—not technically bias, but it behaves
similarly. A confounder is a third variable that's related to both the exposure and the outcome.
Like, if we’re studying coffee and heart disease, but we forget to adjust for smoking (which is
linked to both), our findings could be way off.
The real challenge is that bias isn’t always obvious. It hides in design flaws, data collection, or
even in how we analyze the data. That’s why we were reminded to always think critically: How
was the sample chosen? How was exposure measured? Were confounders adjusted for?
