Distortions of reality: Representativeness and Relativity

Stereotyping and the mass following effect.

The human brain is prone to generalize limited information, often falling into representativeness bias.

This error occurs when we observe isolated behavior in individuals of a specific group and quickly assume that all its members act the same.

For example, when we see several elderly people having difficulty with their smartphones, society creates the unfounded stereotype that the elderly are totally incompatible with modern technology.

Another irrational behavior derived from group influence is the herding effect.

If we walk down the street and observe two adjoining ice cream parlors, one with a long line of customers and one completely empty, we will instinctively line up in the longer line.

We assume without evidence that massive demand is synonymous with superior quality, ignoring that the empty shop might offer exceptional products that we have simply not dared to taste because we blindly follow the decisions of the crowd.

Fluctuation of perceived value depending on the context of presentation.

Finally, our financial eva luation is strongly distorted by the relativity bias.

We do not judge the value of money absolutely, but measure it according to the immediate context.

Suppose we are about to purchase headphones for fifty dollars and a salesperson informs us that fifteen minutes away they are offered for thirty dollars.

It is highly likely that we will make the trip to take advantage of that substantial discount.

However, if we are buying a two thousand dollar laptop computer and are informed of an identical twenty dollar discount at another distant location, the vast majority of us will decline the offer and pay full price without hesitation.

Although in both scenarios the monetary savings is exactly the same, our minds perceive that taking twenty dollars off a monumental sum is a minuscule and irrelevant benefit, demonstrating our deeply irrational nature in managing resources.

Summary

The brain generalizes limited information to create misleading stereotypes rather quickly. In addition, the human tendency to mimic crowds drives decisions based on social pressure.

The relativity bias demonstrates that we value discounts according to context. Identical monetary savings seem crucial in minor purchases, but irrelevant in monumental expenditures.

People judge value by relative and wholly social comparisons. Understanding these perceptual illusions allows us to design attractive offers and avoid conflicts arising from misunderstandings.
