Decision Styles: Are Some Better Than Others?

I was excited to find a new study about decision styles and how they relate to decision qualities.

We know that people have different ways of approaching decisions – or different decision styles. Several studies have suggested the existence of five distinct styles:

baddecisions

1) Rational
An example item in a questionnaire would be:
“I make decisions in a logical and systematic way.”

2) Intuitive
E.g.,“When I make decisions, I tend to rely on my intuition.”

3) Avoidant
E.g.,“I avoid making important decisions until the pressure is on.”

4) Dependent
E.g.,“I rarely make important decisions without consulting other people.”

5) Spontaneous
E.g.,“I generally make snap decisions.”

One big question is: are some of these styles better than others? Or in other words, can decision styles distinguish between “good” decision makers and “bad” decision makers? It would be interesting to know, for example, if decision makers with a more “rational” style generally make better or worse decisions than people with a more “intuitive” style.

recent study by Nicole Wood and Scott Highhouse attempted to answer exactly this question. They found some interesting answers indeed:

  • While intuitive decision-makers rated themselves as the best decision makers, their peers did not agree with those high opinions. It was on the contrary the rational decision style that was related to higher quality decisions, when the decisions were judged by others, rather than the decision makers themselves.
  • None of the other decision styles (avoidant, dependent, or spontaneous) explained much difference in decision qualities at all. Only the avoidant style was somewhat related to low self-ratings, but with a small effect size, and none of those decision styles were related to peer ratings in any way.

Additionally, the researchers looked at personality styles, which have been much more extensively studied in the past already, and are at this point better understood than decision styles. They found that conscientiousness, as a personality trait, is also a characteristic of people who are judged as good decision makers by their peers.

To put this most recent study into perspective: the new findings line up well with previous research supporting the idea that careful decision processes lead to good outcomes. For example, it is already known that careful decision makers are more satisfied with their careers, and that they perform better in school. There are also several studies showing that rational thinkers are less likely to be tricked by typical biases and errors that most people fall for.

Taken together, there is a growing body of research suggesting that careful decision-making predicts decision quality in a number of contexts, and that a rational decision style is effective and beneficial in many areas of life.
