Sometimes the simplest solution is the right one.

You've likely had computer problems in the past. We all have at some point. But what did you do? Did you immediately call up the IT department in a panic? Or did you use the tried-and-tested method of "turning it off and on again"?

This method of measurement has its origins in carpenters' ages-old habit of using the tip of their thumb to estimate an inch. In fact, in Dutch (along with several other European languages), the word for thumb – "duim" – also means inch.

Heuristic methods are reliable and convenient mental shortcuts that you can use to narrow down your options when you're faced with several different choices, to ease your cognitive load , or to solve problems.

Perhaps you're a hiring manager, and you decide to dismiss any résumés that contain spelling mistakes.

In both instances, you are using an heuristic method to meet your objective.
