WebAIM: Writing Clearly and Simply:
"8. Avoid slang and jargon
Slang and jargon can be useful to people who understand it, but confusing to people who don't.
Bad example: Social theory jargon:
Critical theory seeks to problematize the hegemonic reification of oppressive stratified social constructs.
The above sentence accurately describes one aspect of the social movement known as critical theory, but it uses terms that are somewhat less common outside of critical theory, and which have specific meanings within the theoretical perspective. The example sentence may confuse people who are unfamiliar with critical theory."
