To move to the area of evidence-free speculation, it seems to me that
there are reasonable grounds to expect that a hot hand could be a
real, verifiable phenomenon, but only under specific circumstances.
The circumstances are that the skill involved requires repetitive
performance, and precise control of eye-muscle coordination. Examples
where it would be expected might include golf drives, tennis serves,
vollyball, and, especially, free throws in basketball.
My analogy is firing an artillery shell at a distant target. The
first shots of the gunner miss the target. But with each shot, he
adjusts the aim, shifting it slightly to one side, and elevating or
lowering the gun slightly. But once the shells start hitting the
target, the gunner does what he did before and gets the same result.
So it may be with free throws in basketball. Once you succeed, you
have the information about aim and muscle coordination which will
allow you to reproduce your success. Just do what you did before and
you've got it again. Ergo, you have a hot hand. Eventually, your
muscles tire, your aim drifts off target, and you start missing
again. But a success can bring it back for a while.
So, like John, I'm not surprised that a hot-hand could be
established. I'm more surprised that it hasn't been found (accepting
Claudia Stanny's critique of the JEP study).
