What It Is

A stand-alone button, or reaction, that expresses thanks and gratitude.

What It Does

Being assigned to receive thanks increased two-week retention of Wikipedia contributors by 2 percentage points on average for newcomers and experienced participants across communities (p < 0.001).

When To Use It

This works as either a react icon for when users may 'like' content, or as a stand-alone button beneath content.

How We Know It Works

How It Might Work

According to a study by Cornell's Citizen & Technology Lab, they: "organized 344 volunteers over the last year to thank 2,702 contributors to Wikipedia in Arabic, German, Polish, and Persian languages." They found that organizing volunteers to thank others both increased two-week retention of newcomers and experienced contributors by 2 percentage points on average, and caused people to send more thanks to others by 43% on average.

Our Confidence Rating


A grade of Likely is given to interventions that someone has rigorously experimented, published their methods and data, all without a conflict of interest being present. However, it is still awaiting peer review, i.e. it is a preprint.

This is the third highest grade that we give interventions.

In The Wild

This intervention has precedence, and exists, or has at one time or another, existed in the wild.
