How people judge competence, and how to come across well
How people decide who seems smart and competent, and the honest ways to come across that way. Learn what the research shows about these snap judgments — thin slices (impressions formed in seconds) and how accurate they are; why plain words and clear writing make you seem more intelligent than big ones (Oppenheimer’s “needless long words” studies); how voice, pace, fillers and eye contact change how capable you sound; why asking good questions and asking for advice raise others’ opinion of you; calibrated confidence versus overconfidence, and when “I don’t know” helps; warmth versus competence, and why humblebragging backfires; explaining clearly despite the curse of knowledge; and how to listen and build on others in meetings and interviews. The line is drawn at honest signaling — showing what you actually know well — never bluffing, and the skill covers the Dunning–Kruger effect and the critiques of it. Every item is a realistic scenario or a named finding with one defensible best answer. Distinct from Charisma (warmth and presence), Precise Expression (word choice) and Public Speaking (delivery to an audience). Educational skill practice — it is about how others perceive competence, not a measure of your intelligence.
