"Have you ever noticed that....."

Reason follows logic in explanation?

What I mean is, that you may make a decision in an instant and when asked could/would provide a multitude of reasons that are applicable and inclusive to the conclusion, but..... it could take minutes to provide these, maybe days, or much longer.

The reason being that this process is so much longer is - Storage/Retrieval.

This identifies the concious region involved by implication - Conciousness.

The concious state is only limited in it's knowledge/understanding because we have a much older and better established and proven highly successful protective state that precedes and controls it. How do we know this?

Your memory is limited - by choice

It May Appear Instinctive or..... Pre-meditated

The Unconcious mind is tasked with the 'operational' - purpose - exist/exchange information.

Competitive factors are involved, but all, ultimately, self serving in both individual and co-operative primordial respects.

Or, to put it another way, sometimes you do what you do because there's a reason that it suits you. You may mention and discuss it for comparison (what would you do? scenario). If you don't, you don't require the feedback information from a comparable debate.
