In a blog post I read the warning about candidates exaggerating their insight by using lot of jargon. It was about Lean Management. The author stated that when recruiting, mastering enough Lean vocabulary is important in order to catch candidates exaggerating their insight by using jargon. Any talented Lean manager can explain the same concepts without Lean management specific language, the author wrote, but inexperienced or unskillful interviewees may lean (pun intended?) on “concept-dropping.”
Even so I agree with everything above, the heavy use of peculiar lingo is not specific to Lean and Lean “experts” are not even the worst.
I remember a recent (July 2017) conference in which a speaker delivered a pretty convincing presentation about a somewhat uncommon approach we are familiar of. One of my colleagues, intrigued, went to see the speaker and asked him a question on a specific aspect only a true experienced expert could answer. This very question reminded the speaker of an important call he had to make and he vanished. He was indeed only “concept-dropping”.
Nothing really new. Molière, our most famous (French) playwright and actor (1622 – 1673) used to ridicule the physicians of his time in several of his works. Those experts were depicted as pompous and disputing in fantasy latin about this or that just to impress their audience or others fellow “experts” with fake erudition, while their patients usually were bleeding away.
In French slang, a “faisan” (pheasant) is a crook, a good-looking but stupid pretender. I used to hear fake experts being called “faisans”. Nice feathers, but that’s barely all.
