Cerebral Palsy maybe/maybe not

OK, take this on faith (for now) and you will be ahead in spotting misleading information. Whenever you want to find out something about something [NO EXCEPTIONS], you must first decide what is a reasonable scope of expectation.

This is the RULE OF REASONABLE EXPECTATION !

Before you study anything, or get ready to hear any study, have a clear idea of what could be possible, even at the edge of broad experience. Why? Because that dictates what is required of the tool used to measure whatever happens. You won't measure the temperature on Jupiter by licking your finger and pointing at Jupiter. Trekking in Antarctica? Bring a candy thermometer? Measure varus of the hind foot? Is a lateral x-ray of the foot able to even approximate a clinically meaningful deviation? No, it isn’t. And yet those 'results' were reported. How tight a measurement is needed to change the way shoes are made or reinforced. If the x-ray sensitivity can barely detect a change of 30 degrees, is THAT enough to make clinical declarations? Is it even ethical to radiate 1000 children with x-rays looking for that totally insensitive answer? That happened. Almost every organized human endeavor that measures things or studies things uses this rule. Unfortunately, it is given a different name in nearly every context or field of application. We already hinted at where this is going. There is SIGNAL (within the scope of what we want). There is NOISE, that which makes signal hard to see or detect or which bedevils our detection tools.

Here’s an example where common sense & reasonable expectation & assumption prevents flawed conclusions.
