Consider 'trial and error' as a learning strategy, not just a random process.

Learning Method

'Trial and error' suggests an informal approach to solving problems.

Informality

Use 'trial and error' to describe hands-on activities, rather than purely intellectual ones.

In psychology, 'trial and error' refers to how behaviors are learned by experiencing what does not work.

When in a psychological context, it is about observing learning patterns over time.

'Trial and error' in psychology is used systematically, like in scientific methods.
