Another real challenge is being able to continue to fund failure. Always seek external funding before you think you need it! When you are forced to put your rent on your charge card your tolerance for failure decreases significantly.

Very interesting. I would be interested to see the exact phrasing of your Mechanical Turk question, to ensure that there is no bias hiding in the wording. I would also be interested in rerunning the experiment with two groups, one who sees the DA's argument and one who sees your argument, and seeing how much these arguments skew the numbers for each self-assessed Math/English segment.
