Should you think fast or slow? Some people say your Zen like first instinct reaction is the correct one. And that's a legitimate point of view.
Some people say no – saying that your first instinct is almost always wrong and you should stop and think carefully.
Thinking Fast and Slow is the title of this book by Daniel Kahnemann. He delights in pointing out how simple tricks like anchoring bias affect people's cognition. The book lists several other cognition failures that produce incorrect short-term judgment. It's worth reading to get an idea of these pitfalls.
Both schools of thought - be Zen, be cautious - probably have merit.
