My suspicion is that they would argue that in practice, the information would leak out before then and minutely affect your conscious perception (like, even if you don't look at the disk, the light reflected from it or the light from the laser writing it will somehow affect your perception). Obviously this is just avoiding the problem.
I want to know how the idea ties in with evolution, though.
It doesn't tie in directly to evolution, but the misconceptions are related.
I received my fair share of nonsense 'facts' growing up, and I had a hell of a time autodidacting myself as an adult - mostly because some of the consequences of our scientific knowledge base are never explicitly said. Here's a brief list of high-probability truths I've had to infer:
-'Observer effect' is a quantum-level mechanism, not a conscious entity.
-Schrodinger's cat would not be a superimposed waveform, the waveform would have collapsed immediately (likely leading to a many ...
We're all familiar with false popular memes that spread faster than they can be stomped out: You only use 10% of your brain. Al Gore said he invented the internet. Perhaps it doesn't surprise you that some memes in popular culture can't be killed. But does the same thing happen in science?
Most of you have probably heard of Broca's aphasia and Wernicke's aphasia. Every textbook and every college course on language and the brain describes the connection between damage to these areas, and the speech deficits named after them.
Also, both are probably wrong. Both areas were mistakenly associated with their aphasias because they are near or surrounded by other areas which, when damaged, cause the aphasias. Yet our schools continue teaching the traditional, erroneous story; including a lecture in 9.14 at MIT given in 2005. Both the Wikipedia entry on Wernicke's aphasia and the Wikipedia entry on Broca's aphasia are still in error; the Wikipedia entry on Wernicke's area has got it straight.
Is it because this information is considered unimportant? Hardly; it's probably the only functional association you will find in every course and every book on the brain.
Is it because the information is too new to have penetrated the field? No; see the dates on the references below.
In spite of this failure in education, are the experts thoroughly familiar with this information? Possibly not; this 2006 paper on Broca's area by a renowned expert does not mention it. (In its defense, it references many other studies in which damage to Broca's area is associated with language deficits.)
So:
