Chapter: Helpful Shortcut or Harmful Bias?
Helpful Shortcut or Harmful Bias?
Intuition is the ability to understand something immediately, without the need for conscious reasoning. The role of intuition in effective decision-making has long been celebrated by leaders who “trust their gut” as well as by cognitive scientists who have documented evidence that intuition can help “cut through the noise” of crippling and conflicting information overload.
Intuition is a very powerful thing, more powerful than intellect, in my opinion.
—Steve Jobs
In his book “Thinking, Fast and Slow,” the famed cognitive scientist Daniel Kahneman (2011) explains the way we make decisions as a process that uses two different but complementary systems:
- System 1 is fast, automatic, and intuitive—essentially, your “gut instinct.” It takes little to no cognitive effort and is how we incorporate emotion into decisions.
- System 2 is slow, deliberative, and intellectual. It enables abstract, complex thinking but also takes significant cognitive effort.
Unsurprisingly, our brains look for the path of least resistance and take shortcuts whenever possible by relying on System 1. The wonderful shortcuts of System 1, called heuristics by cognitive scientists, make getting through each day possible by highlighting patterns and simplifying questions. They are how firefighters make in-the-moment decisions when the speed of action, not the optimization of action, will save lives. When we have built up a lot of expertise on a topic, this tendency works out great. We can follow our intuition, trust our gut, and find ourselves on the right side of a decision most of the time.
But sometimes, these shortcuts can go wrong.
There are times when we over-rely on System 1 and leave out important information. This leads to bias, one of the greatest derailers of good decisions. Bias creeps in when the models we create in our minds are oversimplified or inaccurate. Good decisions, especially for complex and high-stakes situations, must rely on a combination of both systems (Figure 2).
To make sure System 1 is not leading you to a biased decision, take a moment to intentionally rev up System 2. Ask yourself critical questions about the situation and how you came to your decision:
- Is something about this situation new, so that my past experiences may not apply?
- Is the situation more complex than usual? Am I avoiding the complexity because it seems too daunting?
- I am having a strong emotion. Is the emotion guiding me to something important missing from the data, or is it leading me to irrationally override irrefutable data?
- If this is one of the times that intuitive thinking is wrong, how bad will the consequences be?
More information about the biases that derail decisions are in the Appendix, “Cognitive Biases.”
Long Description.
The Venn diagram consists of two circles intersecting with each other. The circles are labeled System 1 and System 2. System 1 lists Gut instinct and Fast but Risky and Susceptible to bias. System 2 lists Critical thinking and Complexity but Too slow and Leads to fatigue. The intersecting part reads 'Good decisions.'
