Tell us your phobias and we will tell you what you are afraid of.

Benchley’s line is a dry joke about the pseudo-scientific confidence of popular psychology and self-help “diagnosis.” By pretending that a person’s phobias need decoding—when a phobia is, by definition, a fear—the speaker exposes how some explanatory systems merely restate the obvious while sounding authoritative. The humor comes from the bait-and-switch: it promises insight (“tell you what you are afraid of”) but delivers a tautology. More broadly, it satirizes the human desire to translate anxieties into neat labels and the market for experts who offer certainty without adding understanding.
