Only the real science approach ever works. If your &quot;science&quot; is using any other approach, it is not a science, period.<p>And there is a proper, scientific approach in the economics: behavioural economics. Instead of hand waving about some &quot;ideal&quot;, non-existant agents acting fully rationally upon a 100% correct and impossible information available, as the classic bullshit economics does, the proper, behavioural economics starts with studying the real individuals behaviour (which is very much doable, no matter what the others are saying), and only then drawing conclusions about the herd behaviour in a statistical scale.
