fun fact. My school liked to have the students plot out studies and conduct them on the class to teach us about how to do them right. These fat girls got together and wanted to prove they were more effective learners listening to their ipods and eating non stop. I ended up in their group because the teachers knew I was a smart and crafty bitch and I wasn't gonna fail for these fat fucks, so I took their premise and actually helped build something out of it. No mater what sort of music it universally reduced performance, but we found that the results for food were quite interesting. The first we did was cookie or doughnut, which had the absolute worst results, worse then the pop with lyrics which was the worst in the music category, followed closely by bran muffin or bagel. ice chips in water gave the same as our control, carrot or green pepper gave better odds that they argued were so marginal they had to be a fluke, but even they could not contest the watermelon and grape category. in math it increased the results by about 68%, and in the spelling test it was 150% improved! I was fucking stunned, I thought that was a fluke and so did the teachers, so we got to expand our sample size to the whole school on that, and the results did not significantly shift. TL;DR veggies are good but fruit is the best for increasing focus and performance in meetings
