Fun-with-Evidence Friday: Science works, b!t3^&s!

Sciencetee  Spotted this great t-shirt in Berkeley, California. Evidently the creator made this to summarize his doctoral research: Science: It Works, B!t3^&s.  Sciencetee2







What does "clinically studied" mean? (A cynic might interpret that as "research funds were spent").  I happened to see GNC's Mega Men Sport multivitamin, labeled as a "Clinically Studied Multivitamin^". Labels are small, so detailed findings can't appear on the front of a consumer package. But I wondered about the meaning in this context. Here's what the product page says.

Clinicallystudied"Lutemax 2020™
^In a randomized, double-blind, placebo-controlled study of 112 healthy volunteers, subjects taking the GNC vitamin and mineral blend in this product for six weeks experienced statistically significant improvements in markers of B vitamin and antioxidant status, as well as improvements in SF-36 Vitality and Mental Health scores compared to those taking a placebo."

And there you have it: A little evidence of something or other.

Happy Fun-with-Evidence Friday, everybody.


Thanks to reader JSB for this background on the t-shirt: "The t-shirt image graphs two things: a theory and a reality/ actuality/ fact.

- Solid line=the theoretical energy density of cooling hot matter, a.k.a. Black Body Radiation ("Author" of theory: Max Planck, year 1900 CE).
- Dotted line=actual density of electromagnetic energy astrophysicists measure passing through the Universe, a.k.a. Cosmic Background Radiation or "Big Bang Afterglow" (Author of Bang unknown, c 13.8 BYBP)."

Evidently this tee was explained on Explain XKCD.

Rob: Heh. Yes, there's gotta be a pony in there somewhere!

"A little evidence of something or other." Well stated. "I'm sure that there's a small p value buried in this data someplace."
