Narratives are Broad, Intuitions are Specific


A colleague recently asked me about this sentence in our 2017 article on Two Minds Theory: "people often make one type of decision based on the gist of health information presented (narrative system) but another based on specific details (intuitive system)." He questioned whether this was really true -- wouldn't the Narrative mind be the one that gets the details right, and the Intuitive mind be the one that glosses over them? I still think that my original description of the systems is right, that narratives are broad while intuitions are specific. I'm sharing my argument below.

The narrative system (Kahneman’s System II) is the logical, rational mind, so I can see why that might seem tied to specifics, while the heuristic-driven intuitive system (Kahneman’s System I) might seem more vulnerable to errors based on poor attention to data. But in fact I see the intuitive system as excessively driven by details, including some that might not be important. It tends to miss context or meaning. For example, the intuitive mind produces anchoring effects, like when the first dollar amount named in a contract discussion becomes the basis for further haggling and negotiation. The intuitive mind might say “that’s too much,” but its reaction doesn’t lead to stepping back and asking what’s a reasonable price or what others are charging for similar products/services in the community. So if I say I will charge you $1,000 to give a talk, you are likely to negotiate and I will eventually come down to a price of $800 or $900, but you probably won’t come back and counter-propose $150 based on some set of first principles. A lot of biases work this way, using first impressions or making decisions based on characteristics like color, shape, etc. that we might not even be consciously aware of. The implicit association test is about how one’s mind perceives and reacts to details (e.g., black = bad) in ways that aren’t justified and are probably outside conscious awareness. And Richard Thaler’s work is a good example of how we can “nudge” people’s behavior by manipulating the details, e.g. via product placement in a store to encourage particular types of purchases. In all of these System I examples, the details are what dominate. 

 The narrative mind, by contrast, tells a story. It’s the part of the mind that’s able to step back and say “here’s the overall goal we’re trying to accomplish, and here are some things that are getting in the way,” or the part of your mind that makes a list before you go to the store and then crosses off items as you find them. The System II story does include some details (e.g., the items on the list), but the overall narrative is what matters (“I’m going to purchase what’s on my list, and not make impulse buys”). As you walk through the store you probably aren’t mentally rehearsing the list, especially if you gave it some narrative structure beforehand by sorting items based on different sections of the store. When you get to a particular item, you might notice if they don’t have your usual brand but you will probably buy a substitute; what you wouldn’t do is say “they don’t have what I want” simply based on the color or shape of the box. The intuitive mind would do those things, while the narrative mind is able to get past them and see two different items as similar based on their shared meaning or purpose. 

 As further proof that the narrative mind is not detail-oriented, think about whether you dream in color. Most people say yes, but during the period in the mid-20th century when TV and movies were mostly black and white, most people actually said no! The truth of the matter is that I have no idea whether I dream in color, I just wake up with some idea of what I dreamed about and my brain fills in the details based on what seems to make sense. That’s what I mean by the gist. It’s also why I cn rd ths sntnc wtht vwls, because my brain is able to fill in the missing parts based on the overall sense of what’s being said. The narrative system is detail-insensitive, although it is so good at pretending it knows the details that we often miss this fact. That’s why stereotypes are pernicious – they provide such a reasonable-seeming story that we notice only those details that support it, without paying attention to those that don’t. 

I think that Kahneman misses the boat by arguing that System I is usually the source of problems, and System II is usually the solution. In my view each system has its own strengths and weaknesses, and different types of errors arise from each source.

Prototypes and Willingness: The Theory of Planned Behavior Revisited

  You may recall my blog post from last year on the Theory of Planned Behavior (TPB) , titled "in praise of a failed model." My evaluation of this model was that it accurately describes the Narrative Mind, which does control intentions. But the ultimate goal of the TPB is to predict behavior, and the relationship between intentions and behavior is weak at best -- in fact, it is entirely attributable to the fact that when someone says they don't intend to do something, they probably won't do it. When they say they do intend to do it, their actual results are no better than chance, a result of the intention-behavior gap as described in Two Minds Theory.  The full TPB is shown in this diagram: Cognitive constructs like attitudes, subjective norms, and perceived behavioral control (i.e., self-efficacy) are Narrative-system phenomena, and they do indeed have relationships with each other and with intentions (which are also products of the Narrative Mind). Perceived behavi...

Leventhal's Common-Sense Model and Two Minds Theory

Leventhal, Diefenbach, and Leventhal's (1992) "common sense model" of self-regulation. My 2018 paper describing Two Minds Theory (TMT) cites work by my colleague and coauthor Dr. Paula Meek, who conducted studies of patients experiencing the symptom of breathlessness due to chronic obstructive pulmonary disorder (COPD). Paula's research used a model by Howard and Elaine Leventhal (with Michael Diefenbach) that was an early iteration of the dual-process approach also used in TMT. She found that people who focused their attention on different aspects of the feeling of breathlessness then in turn had different interpretations of what that symptom meant for them, and that those interpretations changed their perception of the symptom's intensity. This example illustrates a back-and-forth between perceptions and thoughts, which is characteristic of Leventhal's model. Leventhal's dual-process model, sometimes called the "common sense model" of self-reg...

Intuitive Decision-Making by People with Diabetes

People with diabetes often find it challenging to maintain their blood sugar levels, in part because diabetes is a complicated disease. When the kidneys don't produce enough insulin fast enough to adjust for changes in digestion or activity, blood sugar can fluctuate rapidly, even over the course of a single day. To manage this, people with diabetes often need to make changes in multiple areas: adopting a low-carbohydrate diet, managing the timing and amount of exercise they get, keeping track of the times when their blood sugar rises and falls, potentially giving themselves a dose of insulin around mealtimes, managing stress, and other preventive measures as well.  But despite all of this complexity, the people who manage their diabetes most successfully are often the least  obsessive about the fine details. When my Dad was first diagnosed with diabetes, he checked his blood sugar often (using finger sticks; continuous glucose monitoring [CGM] devices weren’t yet a thing). Bu...
