{"id":1098,"slug":"overconfidence-in-house-comparator-pattern-for-gc-pitches","title":"The \"my nephew can build it\" pattern — loss-aversion on the invoice + overconfidence on in-house execution as mechanistically linked","kind":"reference","scope":"business","status":"current","audiences":["kevin","candid-team"],"topics":["gc-vertical","psychology-aversion","entrepreneur-cognition"],"reference_body":"**Claim (applied inference):** GC owners simultaneously display loss-averse cognition toward a Candid invoice and overconfidence about an in-house alternative (\"my admin can build the site,\" \"my nephew does this stuff\"). These are not contradictory — they are mechanistically linked.\n\n- The **financial decision** is evaluated in the loss domain against the steep value-function slope ([[kahneman-tversky-prospect-theory-loss-aversion-2to1]], [[brown-imai-vieider-camerer-2024-meta-analysis-lambda-1955]]).\n- The **in-house execution decision** is evaluated in the gain domain through a representativeness heuristic ([[busenitz-barney-1997-entrepreneur-vs-manager-overconfidence]]) that compresses the actual probability of execution failure ([[cooper-woo-dunkelberg-1988-entrepreneur-overconfidence-81pct-33pct]]) via reference-group neglect ([[camerer-lovallo-1999-overconfidence-reference-group-neglect]]).\n\nThe cheapest Candid pitch to defeat is one whose comparator is \"having my cousin do it\" left implicit. Pitches must **surface the comparator explicitly** and reframe the in-house alternative as a *bet*, not as a default no-cost option.\n\n**Confidence:** Applied inference from the underlying overconfidence literature. Research gap: no field studies specifically on owner-operator construction businesses evaluating in-house alternatives to professional services ([[risk-aversion-brief-research-gaps-may-2026]]).\n\n**For Candid:** The question to put on the table is not \"will you hire us?\" but \"**what is your plan and what is the probability of execution failure?**\" The cousin-builds-it option has a probability of failure too, and the comparison is genuinely apples-to-apples once both sides are made explicit. Most GCs have never been asked to evaluate the in-house option against its base rate.\n\n**Operationalized as:** [[rule-surface-and-reframe-in-house-comparator]].","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"research-brief-risk-aversion-post-failure-may-2026","title":"Research brief: risk aversion, loss aversion, and post-failure decision patterns in GC and trades-business decision-makers (May 2026)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"camerer-lovallo-1999-overconfidence-reference-group-neglect","title":"Camerer & Lovallo 1999 (AER) — \"reference-group neglect\"; entrants over-enter when ranking depends on skill, lose money in most rounds","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"cooper-woo-dunkelberg-1988-entrepreneur-overconfidence-81pct-33pct","title":"Cooper, Woo, Dunkelberg 1988 (JBV) — 2,994 entrepreneurs; 81% rated odds of success 7+/10; 33% rated 10/10 vs ~50% 5-year base-rate failure","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"busenitz-barney-1997-entrepreneur-vs-manager-overconfidence","title":"Busenitz & Barney 1997 (JBV) — entrepreneurs score significantly higher than corporate managers on overconfidence and representativeness","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"kahneman-tversky-prospect-theory-loss-aversion-2to1","title":"Kahneman & Tversky prospect theory (Econometrica 1979; JRU 1992) — loss aversion ratio ~2:1; fourfold pattern; certainty effect","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"brown-imai-vieider-camerer-2024-meta-analysis-lambda-1955","title":"Brown, Imai, Vieider, Camerer (JEL 2024) — meta-analysis of 607 loss-aversion estimates; mean λ = 1.955, CI [1.820, 2.102]","kind":"reference","scope":"business","link_type":"depends-on"}],"incoming":[{"slug":"bounded-vs-implicit-loss-frame-distinction","title":"Bounded-loss vs implicit-loss frame — implicit (\"you'll fall behind\") fails; bounded (\"max exposure $X, kill points at month 2 and 4\") works","kind":"reference","scope":"business","link_type":"depends-on"},{"slug":"rule-surface-and-reframe-in-house-comparator","title":"R4 — Surface and reframe the in-house comparator; the implicit competitor is \"my cousin / my admin\"; reframe it as a bet with its own probability of failure","kind":"rule","scope":"business","link_type":"depends-on"},{"slug":"rule-replace-implicit-with-bounded-loss-framing","title":"R9 — Stop using implicit-loss framing; replace \"you'll fall behind\" with bounded loss (\"specific cost of current configuration over 12 months, in lost leads / wasted spend\")","kind":"rule","scope":"business","link_type":"depends-on"}]},"created_at":"2026-05-25T13:13:30.993Z","updated_at":"2026-05-25T13:13:30.993Z"}
