Copied from the file, not written here

Why expensive, wasteful, effortful, or self-deprecating actions build trust and desire — Rory Sutherland on signalling. Use when the problem is credibility or desirability rather than meaning: the user asks 'why don't people trust us', 'how do we look more credible/committed/premium', 'is our guarantee/warranty worth it', 'should we spend on brand advertising', 'how do we justify a higher price', or wonders why a cheaper-looking competitor wins. Covers costly signals (advertising spend, guarantees, over-delivery), price-as-quality-signal (Veblen goods), and the Pratfall Effect (admitting a real flaw to gain trust). Inspired by Rory Sutherland's *Alchemy*. Routed to from psycho-logic. 日本語の相談（「信頼されない」「安心してもらえない」「強気な価格で売りたい」「広告費に意味はある？」）にも使う。中文咨询（“不被信任”“想以高价出售”“广告费有意义吗？”）也适用。

Costly Signaling — trust is bought with waste

People can't see your intentions, only your actions — so they read your costly, hard-to-fake actions as proof. Anything cheap and easy to fake (a slogan, a claim, a promise) carries little signal. Anything expensive, effortful, or risky to you carries a lot. This is why "wasteful" things work.

The principle

A signal is credible in proportion to how much it would cost a liar. The peacock's tail is useless and metabolically expensive — that's exactly why it's a believable signal of fitness. Apply the same logic to a brand:

Advertising spend is itself the message. A big, visible campaign says "we expect to be here long enough to recoup this, and we have repeat customers." A fly-by-night operator can't afford it. The customer doesn't need to read the ad to get the signal.
Guarantees, warranties, free returns are costly signals: you'd only offer them if the product actually held up. The cost to you is the proof.
Over-delivery and effort ("we'll answer in three rings," lavish packaging, a hand-written note) signal commitment because they obviously cost something.
Price can be the feature. For Veblen goods (champagne, perfume, premium tools), a higher price increases desirability and even perceived performance — the expensive placebo genuinely works better. Cutting the price can destroy the signal.

The Pratfall Effect (the honest-flaw signal)

Admitting a real weakness is a costly, hard-to-fake move — so it reads as honesty, and honesty raises trust in everything else you say.

Avis: "We're number two. We try harder." Owning the weakness made the brand more likeable and more credible than claiming to be the best.
"It's ugly, but it works." / "We're not the cheapest, but here's why." A small genuine flaw makes the rest believable. Perfection reads as marketing; an admitted flaw reads as a person.

How to apply

Read your current signal. Forget what you say — what do your actions cost you, and therefore prove? Cheap claims ("trusted," "premium," "#1") prove nothing.
Find a signal a liar couldn't afford. A guarantee that would bankrupt you if the product were bad. Visible, sustained presence. Effort the customer can see. Real expertise on display.
Consider price as a signal, not just a cost. If trust/desire is the problem, a higher price plus a costlier-looking presentation can outperform a discount. Test before assuming cheaper wins.
Add one honest flaw (Pratfall). State a real limitation plainly. It buys credibility for every true claim around it. Never invent a fake flaw — that's just another cheap claim.
Make sure the signal is honest. A costly signal works because it's tied to reality (you really will honour the guarantee, you really are committed). Faking it is expensive to you and fatal when discovered.

日本語の使用例

「広告にお金をかける意味がわからない、クリックも測れない」→ 広告は支出そのものがシグナル。"これだけ出せる＝続く会社/リピートがある" と無意識に伝わる。直接効果だけで測ると本質を外す。
「強気の価格にすると売れなくなる気がする」→ 信頼・憧れが課題なら値下げはシグナルを壊す。高い価格＋それに見合う見せ方の方が効くことがある（ヴェブレン財）。counterintuitive-tests で検証。
「完璧に良く見せたいのに刺さらない」→ プラットフォール効果。本当の弱点を1つ正直に開示すると、残りの主張全部の信頼が上がる。
葬儀/シニア領域：「安心してもらいたい」→ "安心です" と言う（安い主張）のではなく、追加料金ゼロの明朗会計・返金保証・24時間必ず人が出る など "嘘つきには払えないコスト" を提示する。

Cross-check against the canon

Sanity-check any proposed signal against these; if it contradicts one, name the contradiction and justify it. When a claim is load-bearing or the user asks for evidence or fresh examples, web-search the named theory or case and cite what you find.

Amotz Zahavi, the handicap principle — the biology: a signal is honest because it's costly to fake. If your proposed signal is cheap to imitate, it isn't a signal.
Michael Spence, signalling theory — signals work when they're cheaper for honest senders than for liars; check the cost asymmetry, not just the cost.
Thorstein Veblen, conspicuous consumption — for status goods, price is the display; discounting can destroy the product's actual function.
Elliot Aronson, the pratfall effect (1966) — the caveat: an admitted flaw raises trust only when competence is already established. A struggling brand admitting flaws just looks weak — build the credibility signal first.
