Nice snark. But, the point isn't to trust a Twitter account, the point is to read the actual scientific literature that they linked to...

As others have pointed out already [0] IAT hasn't faired well in the replication crisis.

Of course this doesn't necessarily mean that 'implicit bias' doesn't exist in any form. Absence of evidence is not evidence of absence. I'm just pointing out that saying "a real phenomenon backed up by good studies" in light of recent studies is kind of a stretch.

I usually wouldn't agree with this because plenty of experts have twitter accounts that are more reliable and accurate than text books in their field.

That said, this account doesn't seem to have any provable credentials associated with it and lacks even a first and last name...
