Why two minutes and not five?

Because the number marks the cost of tracking, not the size of the task. Writing an action down, giving it a context, finding it again and reading it costs about two minutes of attention spread over days. Below that, tracking is the more expensive option. David Allen himself calls the figure a rule of thumb.

Does the two-minute rule apply outside the inbox?

It is meant for clarifying: the moment an item is in your hand and you are deciding what it is. Applied all day it becomes an excuse to do small things instead of the ranked ones. In tidemind the rule is offered in the clarify stack and nowhere else.

Does doing small things first not break focus?

During clarifying, no: you are already switching between items, and a two-minute action is cheaper than a two-minute note about it. During focused work, yes, which is why the rule does not belong there. Separate the two sessions and the conflict disappears.

Under two minutes, do it now.

The two-minute rule from Getting Things Done® says: when you clarify an item and its next action would take less than about two minutes, do it immediately instead of writing it down. The threshold is not a natural law; it marks the point where recording, filing and re-finding an action costs more than doing it. Anything longer is deferred to a list or the calendar, or delegated.

“Two minutes” is a guess, and you have never checked it.

The reply that takes two minutes takes nine, and clarifying the inbox turns into an afternoon of small tasks done in the wrong order.

The rule is right. The estimate it rests on is not.

The steps

Clarify to the next action first
The rule applies to an action, not to a topic. “Website” has no duration; “reply to the hosting quote” does.
Estimate, honestly
Not “this should be quick” but “this is one reply, no lookup, no attachment”.
Under two minutes: do it, do not record it
It leaves the inbox without ever becoming a task. That is the point of the rule.
Longer: write it with context and minutes
Then move to the next item. The inbox is not the place to work.
