I could never have imagined myself reading a book by a Nobel Prize-winning economist, but I have, and to my profit. Daniel Kahneman’s Thinking, Fast and Slow has helped me understand more about how I think, make decisions, communicate, and respond to the words and actions of others.
His basic idea is that we have two different modes of thinking and processing information. The first mode is automatic and impulsive. It’s our knee-jerk response that enables us to take short cuts and move on with ease. The second mode is more deliberate, focused, logical, and it’s necessary for making truly wise choices. Some of us tend to react instinctively, go with our guts, and sometimes miss things that are critical. As an ENFP (Myers-Briggs Type), I’m one of them. People need to spend most of their time in the first mode because we haven’t got the time or the stamina to carefully examine every decision we make. Some things just need to be automatic. However, we can become lazy thinkers, and take short cuts when we shouldn’t, and not slow down when we really should.
We are all prone to making snap choices—weighing up people and situations in an instant. We oversimplify, latching on to something we like and assuming that we will like everything. This can lead to major errors in judgment. Let’s say I’m considering someone for a job. I learn that they love fishing, camping and four-wheel driving. This leads me to gravitate towards them. We spend time chatting about our common interests, places we’ve been, experiences we’ve had. I like them. Hence, there is now a bias toward preferring this person regardless of what experience they might have had in the job, how competent or incompetent they are, whether they are a team player or prima donna, or any other critical criteria. This has been called the halo effect. We assume they will be good even though we know very little about them.
Similarly, I might know some details about a person, such as where they trained or who they’ve worked with previously. I associate what I know about them with an ideal that I’ve created. If I’ve had positive experiences with the people they know or with the training organisation they come from, then confirmation bias may lead me to make assumptions about them and not do due diligence to get more relevant information specifically about them. I wonder how many people employed on the ‘it’s not what you know, it’s who you know’ principle, have turned out so differently to what was expected. Taking short cuts might save time in the short term, but may lead to drawn out disasters in the longer term.
Kahneman discusses how we perceive statistics, memories, risks, choices, and more. He shows how our perspective shapes how we respond to things. For example, if a shopkeeper is told that there is a 1% chance that someone entering her shop will be a shoplifter, then she might not worry too much. But, if she was told that of the 1000 people who will come through her shop this week, 10 of them will be shoplifters, you can imagine she will be on high alert for who they might be. The statistics are identical but each statement offers a different perspective.
Context is also important for weighing decisions. If two people are both promised that by the end of the year they will each have a net worth of $100 million, then you’d expect them to be equally happy, wouldn’t you? If one of them was me, I’d be ecstatic. Who wouldn’t be happy with $100 million? If I told you that the other person was Mark Zuckerberg, whose current net worth sits at $75 billion, you can see how context changes everything!
These insights will help us to be more effective communicators. Pausing to consider how people might ‘see’ what we are saying, will move us to take the extra step to get our message across more clearly. So often we think if something has been said then it’s been heard. But is their perception the same as our intention? It pays to be clear and it pays to enquire as to whether we’ve been understood.
Thinking, Fast and Slow is a book to get us thinking about our thinking. While much of what we do needs to be quick and automatic, there are some areas where we need to disengage cruise control and put our minds into manual. In my work as a church pastor over many years I can see times when I took the lazy option and endured the consequences of not thinking hard or long enough. Now, I watch others fall into similar errors of judgment. While we know there is always more than meets the eye and we shouldn’t judge a book by its cover, we get lazy, we’re attracted by the short cuts. I hope that I will grow in wisdom, be a better judge of people, make smarter decisions, and communicate for effectively, as I seek to think both fast and slow.
