SES = Socioeconomic Status

Please clarify your recently self-invented TLA (three letter acronym) at least once in your response to reduce the cognitive load on your fellow reader.

Actually in this case the TLA would be more accurate as a TLA (two letter acronym) because Socioeconomic is just one word only...

You’d better notify https://www.merriam-webster.com/dictionary/SES that this guy made it up and they should remove it from the dictionary

“Self-invented”… hilarious.

This is a relatively common term of art used in discussions of social science (e.g., psychology, political science, economics, etc.).

I probably could have clarified, but I think the meaning should be easily inferred from the context. Plus, it’s easily confirmed with a quick look up (two taps on my phone) or search.

Example of source that shows that it’s not something I just made up:

Invented or not, it’s annoying when someone assumes people reading their comment will know what an acronym from another field means.
