A Branch of Economics

The way human society has developed is based on addressing present problems rather than finding the best solutions from the ground up.

For example, when the manual typewriter was first invented, the keyboard configuration starting with QWERTY was decided upon to slow down the typist because fast typing caused keys to jam.

Now with electronic keyboards, we do not need a slow keyboard configuration. But we are unwilling to switch to a truly better keyboard configuration because we are too invested in the old QWERTY system.

What is the word for this? That we are not finding what is best but just patching that which came before.
