Why Left Search Buttons Perform Faster Than Right Ones

But when designing an interface for finding a note in a small pile of personal notes, or building an app to organize a small team’s working documents, most of the “finding stuff” interface ideas are in play. It’s in these situations where I want to make the argument:  prefer interfaces that let the user incrementally move towards the right ans

Never make the user scroll to find critical information like transactional buttons or important navigation links.

Humans are bad at coming up with search queries. Humans are good at incrementally narrowing down options with a series of filters, and pointing where they want to go next. This seems obvious, but we keep building interfaces for finding information that look more like Google Search and less like a map.

rule similar to the “the fewer clicks, the better” rule is that you must constrain the number of options given to the user; do not make her choose from more than seven options. The reason given for this idea is that humans are incapable of processing more than seven possible choices. Like the “fewer clicks” rule, this rule is wrong.

button presentation should all be tested to optimize results.
