We typically use a combination of data and taste to make decisions.
With data, the numbers suggest one option over another.
With taste, experience and our gut bring us to a conclusion.
In the same way we don’t like the temperature being too hot or cold, we don’t want to lean too far toward data or taste when making decisions, as this can lead to expensive mistakes.
As a general rule, when data is available and it is trustworthy, we should use it.
But even if we have good quality data, we should also use taste as a common sense check when releasing anything new into the world.
