While working on a task, going well with expected outcomes, creates a sense of confidence that we could do anything. After the lunch, you attempt the task and it didn't work - we feel like total disaster.
- Mood swing causes the evaluation to be corrupted. Our reasoning ability is not constant. It changes with time of the day, work pressure, motivation.
- Our brains inability to do computation and holding information at the same time.
For example, you could answer 2 x 2 = ? but
- 22 x 22 = ? (take significantly longer), we know how to compute but we need to hold the intermediate results.
- Keeping a flux benchmark, which is not clear to make decisions upon.
