Only if we can rule out these biases can we begin to think that association may imply causation.

In this ex, both liking science/medicine & liking avocados are both independent reasons for following me on IG — which is the “collider” (I do enjoy both 😂)

When you stratify/sample based on the collider, you induce a false association from being interested in science/medicine to liking avocados.

People who are interested in science may know how healthy avocados are. But we repeat the analysis in a sample of 5000 individuals in the general pop & find no assoc btwn interest in science/medicine & liking avocados.

Next we do a study evaluating whether there is a relationship btwn being interested in science/medicine & liking avocados. We analyze 1000 of my IG followers & find an assoc btwn liking science/medicine & liking avocados. This seems plausible, right?

For ex: let’s say you follow me on Instagram (probably not on Bluesky yet 😂) for only 1 of 2 reasons 1) you are interested in science/medicine or 2) you like eating avocados.

Collider bias occurs when an exposure & outcome share a common effect (the collider). In this case, a distorted association between the exposure & the outcome is produced when we control for the collider.
