Yes. There is a place for well defined neutral terms.
”Growth Mindset” fails the neutrality test. Use of that term necessarily implies that competing educational philosophies must somehow be opposed to growth.
Why would you choose a term which denigrates the related concepts? Simple. You choose loaded language when you are engaged in advocacy: Welfare Queens v/s Families with dependent children. Dreamer v/s Illegals. Voter suppression v/s election security.
When you are engaged in research, you choose neutral language- like “rubric”, or “bypass capacitor”.
To judge them by their current choice of language, schools of education are engaged in advocacy, not research.
