Behavioural Bias
The biggest weakness is not being able to own up to weakness.
How can you set up systems to prevent falling victim of lazy thinking?
📄️ Decision Fatigue
Why do we make worse decisions at the end of the day?
📄️ Reciprocity
Reciprocity bias describes the impulse to reciprocate actions others have done towards us. The desire to return favours, pay back debts and treat others well could have been a decisive evolutionary advantage for humans as it engenders cooperation. However, reciprocity bias can also work in reverse — in response to unfriendly actions, people will deliver back other unfriendly actions!
📄️ Confirmation Bias
System one vs system two thinking.
📄️ Hyperbolic Discounting
Why do we value immediate rewards more than long-term rewards?
📄️ Ikea Effect
Why do we place disproportionately high value on things we helped to create?
📄️ Loss Aversion
The pain of losing feels twice much worse than the pleasure of gaining.
Heuristics
Why do we take mental shortcuts?
Study your biases so you can engineer systems to avoid failing pray to them.
Thoughts 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.
Improvement
Study situations to recognise triggers then practice correcting behaviours and develop systems to avoid the circumstances that lead to poor decisions in the first place.
- Develop mantra as tools for clear thinking in times of chaos and pressure.
- Engineer systems that make it impossible to fall into habits of lazy thinking.
