Measurable beats immeasurable all else equal.

If you could choose between a measurable value or an immeasurable one of roughly the same value, everyone would pick measurable, since it's easier to value consistently to others.

A persistent gravitational pull.

If the amount of value on either side is roughly the same, that's not a tragedy.

But in practice the value on the immeasurable side is an order of magnitude or more larger than the measurable value.

The more that everyone expects everything to be measurable, the more that pull becomes, the larger the immeasurable value has to be to overcome it.

That's a tragedy.

This leads to the phenomena of Serious Business People spending all of their time searching for innovation in the subset of things in the light of easily measurable, missing all of the hugely valuable immeasurable things in the dark.

A tragic industry-scale example of the streetlight fallacy.

In the parable the searcher is drunk.

In real life the searcher is a Serious Business Person that is Data Driven and Results Oriented.
