Direct Replication

Direct Replication

Reviewed by Faisal Zaidi

A repeat of an earlier experiment using its original design, often with larger samples, blinded procedures and several independent labs.

What it is

In the warm-cup literature, repeats with 128 and 177 participants and a three-lab repeat with 861 found no effect.

In effect

In the article on whether a warm drink makes us kinder, the Chabris and Lynott repeats of the Williams and Bargh experiments.

What it does not say

A repeat that finds no effect speaks to the design and samples tested. It does not rule out that warmth shapes social judgment in other designs or settings, and it says nothing about the people who ran the original work.
