We all hear speakers at workshops talk about “mimetic-ideational informational processing”, “episodic memory”, etc., etc.
We consciously DO NOT use a lot of complex terms. We want people to understand and not feel intimidated by information.
When someone uses bafflegab likely that, there’s usually a reason. They may want to impress the reader/listener with how sophisticated their knowledge is. On the other hand, they may want to avoid being accountable for these concepts or terms – “if I drown you in a sea of words, you’ll be less likely to question me and my knowledge”.
We want people to understand and to be able to use what we’re talking about. That’s why we avoid all but the essential terms in our writing and presentations. As Albert Einstein said:
If you can’t explain something simply, you don’t understand it well.
Most of the fundamental ideas of science are essentially simple, and may, as a rule, be expressed in a language comprehensible to everyone.
Milton Smith who coined the word bafflegab defined it as:
“multiloquence characterized by consummate interfusion of circumlocution or periphrasis, inscrutability, and other familiar manifestations of abstruse expatiation commonly utilized for promulgations implementing Procrustean determinations by governmental bodies.”
