The science behind gambling superstitions: It's all about the illusion of control

The science behind gambling superstitions: It's all about the illusion of control | The brain and illusions | Scoop.it
If the average gambler had one wish, odds are he’d want one of two things: an endless supply of cash to gamble or an endless supply of luck to win. Unfortunately, such wishes don’t exist. But many gamblers make do with superstition.
Gerald Carey's insight:

Although this is from a Casino site, it is an interesting set of examples of superstitions amongst gamblers.  Certainly the range of methods that punters use to increase their luck is intriguing.

tom familetti's curator insight, November 5, 2014 4:20 PM

This article is interesting to me because many people are superstitious about various different things, but nothing epitomizes superstition like gambling superstitions!  Whenever anyone goes gambling all they want is some luck. In reality, all that luck you think you are getting from some object or ritual is really your brain trying to fill in the gaps to make it seem like you have control.  This article does a good job of explaining that and giving good examples of gambling superstitions.  In poker luck is less relevant then other games, such as blackjack or roulette, because there is more strategy involved, but everyone still wants Lady Luck on their side!

Pareidolia: Seeing Faces

Pareidolia: Seeing Faces | The brain and illusions | Scoop.it

We have a tendency to find patterns out of normal and meaningless things. One example of this phenomenon is pareidolia: seeing meaningful images in meaningless visual stimuli. If you have looked at a cloud in the sky and perceived a shape of an animal or a face, you have experienced pareidolia. Pareidolia may seem like a harmless and interesting aspect of how the mind works, but it has more influence on society than one would think.

Menu of illusions

Menu of illusions | The brain and illusions | Scoop.it

A variety of interactive illusions. The good thing about them is that you can move the objects in the illusion to show how it is an illusion. For example, in the illustrated illusion (the Ponzo illusion) you would be able to move the green lines to show they are the same length.  There are eight illusions to choose from.

Illusions for survival and reproduction | OUPblog

Illusions for survival and reproduction | OUPblog | The brain and illusions | Scoop.it
Much of what we think we see is not real – it’s an illusion. A favourite pastime for many visual psychologists and artists is to baffle and confuse our perception by making things appear that are not really there, or manipulating the way that we might see patterns or colours. The origin of many illusions lies in the fact that the brain often receives incomplete or conflicting information.
Gerald Carey's insight:

Really good example of an animal using force perspective to create a 'bower' which makes the smaller objects near the front look as big as the larger objects in the rear. Who would have thunk it!

This is the third item that Dave Barlow sent me. He took this photo while on holiday at Fountains Abbey, UK, last year. When he got home he realized there was an illusion that the obelisk seemed as tall or taller than the church.

My question is, how tall is the obelisk seen here?

Taller than the church?
As tall as the church?
3/4 as tall as the church?
1/2 as tall as the church?
1/4 as tall as the church?
