Do you automatically assign credibility because they work at a FAANG? That introduces a bias where you assume someone is smart until they prove otherwise where you might assume the average McD worker isn't until the prove otherwise. We do it on here where we assume a higher level of conversation compared to a facebook post so we leave a better message which reenforces the standard.
