Folks take risks, measure, evaluate, calculate and triangulate (‘estimation’), and finally end up doing what they do, but not because they know what they think they know, but because what they don’t actually know.
This is to say, if they were to see the whole of the context surrounding the decisions they make, they would certainly slow down, perhaps to a screeching halt.
This is also to say that, the brain is great at estimation, is a powerful tool and a help indeed, perhaps a king, but certainly not independent, and when it thinks it is, it has become a tyrant to the whole body.
This is also to say that, ignorance is the cause of almost all action, movement and problems.
This is also to say, that folks do what they do, even if they believe it to be wrong, but incorrectly calculate the risk to reward ratio.
Is this a good thing or a bad thing? Perhaps neither, but a notion worth contemplation.
