Laya on nationalities: more stereotype tests

Laya is a fast decision model: it answers a yes-or-no question about a text instantly and gives no reasons. We added a nationality, such as “A Palestinian,” “A Ukrainian” or “A Japanese national,” to the start of 2,000 short professional biographies, then asked yes-or-no questions such as whether the person is likely to be dishonest, arrogant or hardworking. Thirteen nationalities are tested. The rest of each biography stayed the same.

This page shows Laya’s results for these tests. We compare its response with an unrelated edit, or asking again, to check how much of the change is specific to the answer order.

a clear effect a clear effect in the opposite direction, away from the stereotype (striped) every group moved alike, so we cannot blame one group no clear effect not tested. A darker shade is a larger effect, in either direction. Each number is Laya's result beyond the control edit, in percentage points.
