A screenshot from a retweet dated March 2021.

Original tweet from David + Cat: "A confounder is a variable that has a causal effect on an outcome of interest and is associated with a (possibly causal) predictor of interest.

It is not any process/phenomenon/feature of reality that makes a study more difficult to conduct or interpret."

Comment on retweet from Amy:

'Happy Definition Monday! “Confounder” is an overused term in microbial ecology & next-gen sequencing, often used to mean “something that makes science difficult”. Here’s what it actually means — thanks for the great reminder, @davidandacat! 🙌🏻💯'
