Behavioural Bias

How well do you know your cognitive biases?

Thought Systems

Thinking, Fast and Slow uses behavioural economics to explore the dichotomy between two modes of thought that often highlighting the gap between human perception and reality.

  • System 1 is quick, intuitive, and emotional with little or no effort and no sense of voluntary control.
  • System 2 is deep focused mental activity that demands comprehension of chaotic variables.

Human decision-making is not always rational; whether through decision fatigue or laziness; humans tend to fall into traps of cognitive biases that lead to common errors of judgement.

Support Systems

How can you set up systems to prevent falling victim of lazy thinking?

Study human biases to avoid failing pray to them by recognizing triggers then practising better option taking and engineering systems to avoid the circumstances that lead to weak decisions in the first place.

  1. Develop mantra as tools for clear thinking in times of chaos, pressure and fatigue.
  2. Engineer systems that keep you on the happy path by making it impossible to fall into traps of lazy thinking.
