Good advice is always better when delivered in a British accent:
The animation and briefing on making better decisions in groups is based on the research work of Dr Dan Bang and Professor Chris Frith FRS, ("Making better decisions in groups", Dan Bang and Chris Frith, Royal Society Open Science, 2017, http://dx.doi.org/10.1098/rsos.170193).
The one bit of advice I particularly like is to seek out hidden information. That's essentially how all magic works; concealing by hook or by crook the information that would otherwise allow you to figure out what's really going on. It's not that you're not smart, it's that the information you want is actively being kept from you.
