"Your instinct, rather than precision stabbing, is more about just random bludgeoning"

In this quote, Simon Pegg is comparing two different methods to analytical or decision-making. He suggests that one's impulse, or suspicion, is more about taking a broad and less precise approach, similar to arbitrarily hitting something with a blunt item. This could mean that our impulses are not always rational or calculated, but rather based upon instinct and feeling. On the other hand, precision stabbing implies a more calculated and deliberate method, where one thoroughly aims and strikes with precision. Pegg's comparison highlights the contrast between these two methods and recommends that in some cases our impulses may be more efficient than precise planning.
