Psychological explanation to how traditions are created

The threat of punishment combined with people's willingness to copy others – this is the basis for a new psychological model that can describe how traditions and norms are created and maintained according to researchers at Karolinska Institutet's Emotion Lab in a study published in the Journal of Experimental Psychology: General.

Scientists have shown that animals learn from each other through when there is approaching danger. For example, information about an imminent predator spreads through a flock of birds which then collectively reacts and flees. Yet, the role of social learning in avoiding danger has not been studied specifically in humans.

"We wanted to find out how these situations function in humans when we need to avoid danger. We discovered that two separate, simple, psychological mechanisms – the copying of others behaviour and the rewarding properties of avoiding danger together forms a potent driving force that helps explain how we can create and maintain norms and traditions," says Björn Lindström, researcher at the Department of Clinical Neuroscience.

Along with research leader Andreas Olsson, he conducted four experiments that included 120 test subjects. In the first experiment, the study participants were asked to choose between two pictures, A and B, on a screen 20 times. They were told that an unpleasant (which they had felt beforehand) would be given if they made the wrong choice. In reality, however, no electric shocks were given for any answer. Before making their choice, the subjects were shown a video clip of another person faced with the same choice, without being shown the consequence of the decision. The person in the video choose picture A each time. And so did the subjects in more than 95 percent of their choices. When the subjects were instead promised a reward – a chance to win movie tickets – they adhered to the video person's example in only 60 percent of the cases. In an experiment where there was the threat of an arbitrary punishment, adherence to the example in the video dropped to below 70 percent.

"Our conclusion is that when we are promised a reward, we are more inclined to break the pattern, and social learning tends to play a smaller role. But when it comes to avoiding danger, social learning has a powerful influence on our behaviour when it is proved to yield good results. But in cases where social learning is shown not offer effective protection from danger, we are also more inclined to break the pattern," says Andreas Olsson, docent and research team leader at the Department of Clinical Neuroscience at Karolinska Institutet.

In the fourth study, the researchers wanted to find out whether the inclination to choose only option A could be passed down from one person to the next, under the perceived threat of an electric shock. Ten subjects were separately shown the video in which the person choose option A and were asked to make their choice. Ten new test subjects were then shown video of the choice made by one of the first test subjects, without knowing what the consequence would be. When five generations of had made their choices after watching someone from the previous generation make their choice, picture A remained the chosen alternative in 95 percent of answers.

These mechanisms might help to explain how certain arbitrary traditions can be created and maintained, such as taboos about clothes or forms of behaviour which have no real significance to the group or individual. In this case we created a "choose option A" tradition which remained strong after five generations. Arbitrarily prohibiting certain types of food, for example, that do not need to be avoided for any particular reason, could be maintained because the individuals in the group will tend to fear the disapproval of their group peers if they ate the forbidden food," says Björn Lindström.

subjective pseudo nonsense. where did the desire to be like others arrive from? and the fear of punishment? stop pretending one can tell us what aardvark droppings taste like because you read a book and recognized a pattern

It's called Evolution and there's nothing pseudo about it. Our ancestors who didn't take their cues from tribe mates and didn't fear being killed got eaten by animals and didn't reproduce. What's left is us and our genetic pre-programming, which is about 40,000 years out of date. You should look it up sometime.

I've never tasted aardvark droppings, but if they taste like they smell and you're not a dung beetle, it's probably not a gourmet treat. But, feel free to test this for yourself.

swing and a miss. you've nearly made my point, though. it is clear that im aware of the incomplete nature of this study. the overwhelming majority of thought analysis falls into this trap. correlation is not causation. There are far too many factors at work for this type of nonsense to be accepted.
