But don’t many (most?) US programmers call () parentheses? I assume non-programmers in the US call them brackets?

1.9M results: lisp "parentheses" -brackets

800k results: lisp "brackets" -parentheses

I admit result counts are more similar if lisp is replaced with “python” or “golang”, but square brackets come up more often for those languages.

Disclaimer: I am searching from google.co.nz, and I presume search result counts are not a great proxy measurement for actual usage!
