We treat fluency as a proxy for truth. A clear voice, a clean slide, a confident phrase: we read these as signals of rigour.
Research on what psychologists call the "fluency-truth effect" suggests the opposite: The easier something is to process, the more likely we are to believe it, regardless of whether it is correct.
This is why polished decks beat messy memos. Why the articulate junior gets credit for the quiet senior's idea. Why bad strategies survive long after the data has turned against them. The packaging does the persuading.
The uncomfortable part: this works on you too. When an answer feels obviously right, that feeling is often the fluency talking, not the logic.
That's part of why we built Cognel. Its Guides slow you down where fluency usually wins, and ask you to sharpen and ground your view before calling it done.
When something sounds clean, try to say it back in your own words, even if clumsy. If you can't, the polish, not the logic, was impressing you.
Smoothness is a warning sign, not a quality marker.
