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.
