Why debating the ethics of applying behavioural science is a red herring

Why the debate on Nudge is a red herring (tapped out on my phone during the #LSEnudge debate):

1. We’ve previously designed services thinking everyone is an in-control homo economicus. There’s loads of recent evidence on what we’re like. Why not use it?

2. “They can’t solve everything” is not a reason to not use ‘nudges’. If policy-makers commission ‘nudges’ & don’t deal with the food industry, that’s a problem with policy making, not with decision science.

3. If you want a policy/political narrative for it, work up the idea that we can do politics better if we better understand what we’re like as a species.

4. Behaviour is context-dependent, whether you/others are trying to influence it of not. So it shouldn’t be controversial to try to influence it.

5. There are ethical issues. Why not codify them? For example, behavioural practitioners and their commissioners should only use social norm messages that are true (so you don’t say 95% pay their tax on time if it’s really 80%).
