On Monday I need to give a presentation to a group of 6-15 finance professionals on Confirmation Bias. I intend to use the 2-4-6 task to demonstrate it.

Do people have any advise on how to make this work well? Do people tend to fall for it? Does it help them understand afterwards?

(In ages gone by I would have made this post longer, or in the Open Thread, or not at all. But I gather LW has been seeing a drop-off in volume, so I decided I'd lower the bar I set myself)
