Here’s an example from my own work with firefighters.
It was a study that I did in with my colleagues in 1985. We wanted to know how firefighters make life-and-death decisions under extreme time pressure, when there isn’t time to follow the prescribed steps of generating a variety of options and identifying criteria to evaluate each option. There’s no time when a fire is blazing. So, are firefighters just guessing about how to handle these tough situations in the moment?
We started interviewing expert firefighters—26 of them, each with an average of about 23 years of experience.
As a side note, I remember once being at a meeting and talking about the fact that experience was important for effective decision-making. One of the people in the audience said, “I study decision making in the laboratory and I give my subjects lots of practice.” And I said, “how much practice do you give them?” And he said, “oh, I give them 10 hours of training.” And I thought, 10 hours, as opposed to 23 years? That’s not even close.
We wanted to understand how truly expert firefighters could make decisions, and what they told us was surprising:
“We never make decisions.”
I said “really?” They went on to explain, “You just look at a situation and you know what to do.”
This presented two mysteries:
- How could the firefighters be so confident that they could understand the situation and that the first option would be effective?
- How do you evaluate an option except by comparing it to others, which the expert firefighters said they didn’t do?
As a result of our cognitive interviews, we found that their decisions were built on 20 some odd years of experience in pattern-matching process. They weren’t comparing the patterns; rather, there would be an almost immediate pattern match where they would recognize a prototype of a similar situation from the past.
That’s how the firefighters could respond so quickly and only consider one option— their experience had allowed them to build up a repertoire of patterns in order to quickly size up situations and anticipate which cues to watch, what would likely happen next, the likely goals, and a set of actions that were likely to be successful.
But how do you evaluate the actions? The firefighters would mentally simulate each action, and if the action that they thought of initially would work in their mind, then they carried it out. If it almost worked, they would improve it. And if it didn’t work, they would mentally search their repertoire until they found one that would get the job done.
What we discovered about the expert firefighters’ thought process is an example of what we call Recognition Primed Decision-making, or the RPD model. This model accounts for probably 90% of the decisions people make in tough situations and a much higher percentage in routine situations.
This is just one example of what we’ve been able to learn about human cognition by stepping out of the laboratory into real-world settings.
