Blink versus Think

Should you blink or should you think when taking a decision? We all know why Malcolm Gladwell's view of this is, which is that we make better or rather more accurate decision when we blink.  Michael LeGault has a book, Th!nk: Why Crucial Decisions Can't Be Made in the Blink of an Eye, argues for think and against blinking by asserthing that it is important to ask hard questions and not to lose the ability to think critically about issues. But the question is that I have is whether when we blink, we do not think?
