By 'trivial' error I mean one that's local and easy to confirm and easy to understand. Something that makes you look silly. For example:
- Sign errors in mathematics.
- Forgetting to do a unit conversion in physics.
- Skipping over a number in accounting.
- Off by one errors in programming.
- Fencepost errors in programming.
- Out of bounds errors in programming.
- Null value errors in programming.
- Rear-ending someone at a stoplight when driving.
Some historical examples:
Some anti-examples:
- the Therac-25 bug
- the database concurrency bugs found by Jepsen
Anyways... I'm looking for studies that investigated how often these mistakes happen, and how much the rates vary from person to person. Do some people make lots of them? Do some people make almost none? How much does practice affect the error rate? Are there disorders that affect the rate?
