About reputation.

This is a complex topic. We humans tend to simplify our lives and spare ourselves the effort of thinking by lumping all aspects of a personality together. We look at someone as being "that way", basically "flattening his/her personality", projecting it on one (or more rarely two) dimensions. This is a bias that HR specialists call "the halo effect": we see someone as either "a saint" or "a sinner" whereas people are complex and multi-dimensional

We believe reputation should be associated not with a person but with a skill. Someone is a poor / good / very good cook. A 4.7 star cook. Or bus driver. Or guitar teacher. Or English-French translator. You get the point

Could then "reputation" be seen as an aggregated measure of

1. a skill assessment: how skilled someone is in a given area
2. the precision of the assessmet itself: how trustworthy is the skill assessment?
