Knowing the only places you need to look.

When scientists and engineers create mathematical models for physical phenomenon, they may start with an enormous equation made up of numerous terms. However, many of the terms may show contributions that impact the results on an absolutely infinitesimal scale, so small the it basically rounds to zero. In nearly all cases where this is true, the model is then simplified by removing those algebraic terms. It makes everything easier to handle and easier to change the numbers and check new options.

In that same manner, knowing where to look is an important factor in life. There might be a million possible parameters to investigate, while only two of those parameters have any significant factor at all. In a scenario like that, the person who can see those two important factors will never have trouble understanding the system because they only have two things to take data in about, while others who are focused on the million other parameters can’t possibly keep up with them all. Their brain, their eyes, their ears, do not possess the possible bandwidth to continuously measure all of those parameters and process each of their contributions to the system.

More education and more science doesn’t make you smarter from the standpoint of being creative, it makes you more efficient in processing information because you know where to look and what to ignore and where the edge cases are where some of the factors that you wrote off might become contributors again.
