System 1 - Deepstash





A Nobel Prize Winner Explains How to Finally Think Clearly

System 1 

The focus of this system is: 

  • To maintain a representation of your world. It is an automatically learned skill. For example, driving your car along a familiar route requires little mental effort and is intuitive. 
  • To update a model of your world. It is from the subconscious and based on emotions. For example, when meeting a potential hire for the first time, you will get a feeling for them if they are the right candidate. 




System 1 Thinking

The main function of System 1 is to maintain and update a model of your personal world, which represents what is normal in it.

System 2 Thinking

System 2 thinking informs how you focus on a particular task by using expert knowledge and focusing or applying conscious effort.

Consider driving to work and encountering an accident. This unexpected change demands you pay attention to your environment and monitor your behavior.

How to Use System 1 and System 2 Thinking Together

If you feel a gut reaction after meeting a hire, it's probably System 1 thinking.

But you can mitigate the risk of hiring the wrong person by engaging System 2 thinking. Check their references. Ask probing questions. Validate your gut reaction with other members of your team.

The trick is to be aware of switching from one system to the other. It’s useful to understand when you are thinking on autopilot, when you are paying attention and what's inside your mental toolbox.

The 37%

Mathematics dictates that you should take 37% of the time or options you have to simply look and after that, you should commit to the first option that is better than everything you’ve ...

The brain when we make decisions

The 2 systems of the brain that wok during decision making:

  • System 1 is automatic and quick (like "something feeling off").
  • System 2 is deliberate and slow (like an algorithm).

At times, these systems are at odds with each other, but research shows it's always best to trust an algorithm than your own gut.

Pros-and-cons lists are flawed

There are a few biases they don't address:

  • Narrow framing: the tendency to view an option as your only option.
  • Confirmation bias: our tendency to gather the information that supports our preferred option.
  • Short-term emotion: our tendency to have our judgment clouded when emotions run high.
  • Overconfidence: our tendency to make a decision with too much optimism about how things will play out.
