1331 Trial and error - English Idioms

Explanation

A fundamental method of problem-solving, learning, or discovery that involves repeatedly trying different approaches or methods, observing the outcomes, learning from failures (errors), and adjusting subsequent attempts until success is achieved or a satisfactory result is found.

Origin

The underlying concept is ancient and fundamental to human and animal learning.
The specific phrase trial and error gained prominence in the late 19th and early 20th centuries, particularly through the work of psychologists like Edward Thorndike, who studied animal learning (e.g., cats escaping puzzle boxes) through this process.
It describes a pragmatic, empirical, and often iterative approach to finding solutions when the correct path is not known in advance.

Alternatives

Slang/Informal:

Messing around until it works / Fiddling with it
Winging it (Suggests improvisation with less systematic testing than trial and error)
Throwing shit at the wall and seeing what sticks (Vulgar, crude trying many random things, often unsystematically, hoping one will work by chance)
Playing it by ear (Making decisions as you go based on the situation, less structured)

Milder/Standard:

Systematic experimentation.
Iterative testing and refinement.
Learning through practical application.
Empirical testing.

Situational Appropriateness

Very common and appropriate in almost all contexts – informal, formal, technical, scientific, everyday life.
It accurately describes a fundamental and widely applicable process of learning and problem-solving.

Misunderstanding Warnings

Generally straightforward.
Ensure understanding that error is viewed as an integral and necessary part of the learning/discovery process, not simply as failure to be avoided. Feedback from errors drives improvement.

Dialogue

Dev A: How did you finally get that complex database query to run efficiently?

Dev B: Honestly? Pure trial and error. I kept tweaking the indexes, rewriting joins, and measuring performance until the execution time dropped significantly. Took ages!

Dev A: Been there many times. Sometimes that's just what it takes. Glad you cracked it!

Response Patterns

Agreement, acknowledgment, sharing related experiences, suggesting specific things to try, expressing patience or frustration.
That's often the only way to figure things out.

Common Follow-up Questions/Actions

When discussing a trial-and-error process:

Ask about previous attempts: What methods have you tried already that didn't work?
Inquire about progress: Are you getting closer to figuring it out? / Any breakthroughs yet?
Offer suggestions or share potentially relevant knowledge: Maybe you could try... / I read somewhere that...
Discuss the parameters being tested: What variables are you changing each time?
