Let's say you have two measures meant to capture the same confounder. They're highly correlated. Can you still proceed with your regression analysis?

If you have two measures of the same confounder, you can just include both of them in your regression model
Sometimes, researchers worry about multicollinearity in situations where it’s actually a non-issue. Here’s one such scenario.
Imagine a situation where you are interested in the effect of X on Y (X...

This was a productive episode to do since I remain with the thought that the most important area of science we can be engaged in today is the science of scaling, or the science of using science.

Understanding causality vs. correlation is genuinely hard especially on complex topics like inflation. Our research finds that 60% of Americans think high interest rates cause high inflation & support rate cuts to fight it. But high rates usually respond to inflation,not cause it

How much student learning do you think a school district could gain just by better assigning its teachers to schools?
Consider a quite politically-feasible change. Do not let district make any assigned teacher worse off, nor change teacher hiring, nor compensation, nor the students.
