Next they'll be telling us they don't proofread their title submissions, un-freaking-believable ;0)

PDF link to the important paper, http://pbr.psychonomic-journals.org/content/8/3/622.full.pdf "The persistence of a misconception about vision after educational interventions" by Gregg, et al..

[Mind you Gregg's table 1 has an error too - "reference" should read "refutation" as in the first para on the right column of p.624.]

Now I've a question to ask my 4 year old in the morning!

Would be very interesting to read of results from other cultures, I couldn't see the info in the citation but assume the subjects were local to Ohio. Is extramission belief more prevalent in USA?

What about other unexpected scientific truths like where the mass of wood in trees comes from (most say nutrients in the soil apparently).
