A show all about you…

Why do we still have a headache after taking a 1p aspirin which disappears when we take a 50p one? And why are we attracted to a 2for1 meal discount but fail to save for a pension? Most of the time we think we’re making rational decisions. But are we really?

Don’t miss this entertaining mix of stand-up and neuroscience, as award-winning, five-star author Bernard Ross challenges your assumptions about just how smart you are and explains the rules you follow to make predictable mistakes.

Whether you’re buying wine or trying to lose weight, shopping for food or dating, you overpay, underestimate and procrastinate. Be prepared to laugh and learn – while you learn to stop being predictably irrational.

You’re predictably irrational!

How restaurants manipulate you to spend more

Bernard Ross, the Irrational Guru, explains how this works.


This also happened with Capt Tom & 'it's for the NHS' appeal.

It's interesting that in cases like this, so many people 'default to trust'.

I'd love to see #WooltonPictureHouse survive & *would* give to help that happen.

But tell me how my money will achieve that goal.
