Owner-side mechanism inventory — eight cognitive mechanisms that make a normal new-site ramp feel like failure (anchoring, expectation-disconfirmation, action bias, illusion of control, sunk cost, loss aversion, hyperbolic discounting, availability)

Claim: Eight robust cognitive mechanisms predict that owners of brand-new websites will experience the normal early ramp as failure — and act on that feeling — even when nothing is wrong with the site. The mechanisms compound: an anchored expectation creates the gap; disconfirmation makes it feel bad; loss aversion amplifies the bad feeling; action bias makes inaction feel worse than action; illusion of control says the action will help; sunk cost says quitting wastes everything invested; hyperbolic discounting says the payoff is too far away; availability brings prior bad experiences forward as evidence "this will fail too."

The eight mechanisms, each its own atomic entry:

1. Anchoring (expectation formation) — Anchoring — Tversky & Kahneman (1974), Science: the first number/claim heard becomes a reference point subsequent judgments insufficiently adjust away from; operates even with arbitrary, known-irrelevant anchors.
2. Expectation-disconfirmation (why a normal ramp feels like failure) — Expectation-disconfirmation theory — Oliver (1977, 1980); 2024 meta-analysis (150 records, N=58,597) confirmed positive expectation-satisfaction relationship (r≈.29) with no support for contrast effects.
3. Action bias (the panic-tinker urge) — Action bias — Patt & Zeckhauser (2000), Journal of Risk and Uncertainty: preference for doing SOMETHING over waiting, even when waiting is optimal, because inaction following a bad outcome feels worse, Action bias — Bar-Eli et al. (2007), Journal of Economic Psychology: 286 penalty kicks analysed; goalkeepers jumped 93.7% of the time despite center being utility-maximising (33.3% saves staying central vs. 12.6% right and 14.2% left).
4. Illusion of control — Illusion of control — Langer (1975); REPLICATION-FLAGGED: classic Study 2 failed to replicate in Kühberger et al. (1995, four experiments, none successful).
5. Sunk-cost effect (over-investment in a failing site) — Sunk-cost effect — Arkes & Blumer (1985), Organizational Behavior and Human Decision Processes: ten experiments + theater-season-ticket field study (full-price buyers attended more plays than discount buyers); MONETARY robust, time/effort weaker.
6. Loss aversion — Loss aversion — Kahneman & Tversky (1979) prospect theory; REPLICATION-FLAGGED: Gal & Rucker (2018) challenged universal 2:1 claim; Walasek/Mullett/Stewart meta-analytic re-examinations find coefficient ≈1.3 (or near 1 under symmetric conditions); Kahneman conceded "not a law of human nature".
7. Hyperbolic discounting / present bias (impatience) — Hyperbolic discounting / present bias — Ainslie (1970s); Laibson (1997), "Golden Eggs and Hyperbolic Discounting," QJE; present bias well-supported (commitment-device demand); quasi-hyperbolic functional form contested.
8. Availability heuristic (prior bad experience) — Availability heuristic — Tversky & Kahneman (1973): judging probability by how easily examples come to mind; a vivid prior failed venture makes "this will fail too" feel more probable than base rates warrant.

Confidence: High on enumeration; per-mechanism confidence varies (see each entry — illusion of control and loss-aversion magnitude are replication-flagged).

Caveat: This is the single most useful single deliverable in the brief for client conversations. Owners who recognise the stack in themselves typically de-escalate their own panic without further intervention.
