Why commission changes advice more than dishonesty

An estate agent selling their own house waits longer than when selling yours, and ends with a higher price. No fraud is involved. A commission that is a small share of the price but the whole share of the effort simply makes the last week of patience worth less to the agent than to the owner.

What everyone sees

Conflicts of interest are discussed as an honesty problem, which makes disclosure the obvious remedy. Tell the client how you are paid and an informed client can discount the advice. Regulators like this because it is cheap, and advisers like it because it is survivable.

What is actually happening

The measured effects run through judgement rather than through lying. Compared with client sales, agent-owned homes stayed on the market roughly ten days longer and sold for a few per cent more. Work on disclosure found it can make matters worse: the adviser feels licensed by having confessed, while the client finds it socially costly to act on the warning they were just given.

Why it stays hidden

Nothing here requires bad faith, so nothing here trips the defences built for bad faith. The adviser passes every honesty test, because the recommendation offered is genuinely the one that occurred to them first. That is why the useful question to put to an adviser is not whether they are honest, but how their last hour of attention is priced.
