Surprising and exciting scientific findings capture our attention and captivate the press.  But what if, at some point after a finding has been soundly established, it starts to disappear?  In a special collaboration with Radiolab we look at the 'decline effect' when more data tells us less, not more, about scientific truth.

Correction: An earlier version of this short incorrectly stated that Jonathan Schooler saw the effect size of his study fall by 30% on two different occasions. In fact, he saw it fall by that amount the first time he repeated the study and saw a general downward trend thereafter. The audio has been adjusted to reflect this fact.

Correction: An earlier version of this short incorrectly attributed a statement to Jonathan Schooler’s advisor. The statement was actually made by his colleague. The audio has been adjusted to reflect this fact.
