Ethnocentrism: "the belief and feeling that one's own culture is best." This can also stand in the way of an ethnographer and their work by creating a bias against the society's principles or beliefs.

Though he’s been associated with a very strange idea he never had, Edward Sapir was quite explicit about this loss over a hundred years ago. Thinking specifically about a later passage warning people about the glossocide English language. But it’s been clear in his work from long before that excerpt that we’re missing out when we focus on a single language.

Group privacy is much more infrequently discussed than individual privacy. At least in Euro-American contexts. Quite likely a very important bias.

It’s been obvious in my teaching that a lot of people confuse -centrisms with pride or condescension. Yet it’s possible to be selfcentred and ashamed, or eurocentric and guilt-stricken. My favourite approach to explaining these -centrisms comes from a textbook which defines tempocentrism thusly:

Treating one's historical time period as "normal," or best, or as timeless; failing to conceive how the past or future might differ from the present.

Despite the mention of “best”, the key idea is quite different from comparative judgment. It’s about a failure of the imagination.
