Low legibility of Cognitive Reflection Test dramatically improves performance?

I'm reading Kahneman's Thinking, Fast and Slow and I've stopped on this:

90% of the students who saw the CRT in normal font made at least one mistake in the test, but the proportion dropped to 35% when the font was barely legible. You read this correctly: performance was better with the bad font.

This seems like an important finding, but I can't find references in the book (Kindle) or on the Web. Does anybody know any real evidence for this claim? EDIT: I found the original paper

Do you think that people could behave rationally with such a simple intervention?

A higher cognitive burden on comprehension tautologically requires more thought per unit of information occur.

I don't know if it's a question of rational behavior but of necessary.

I don't think it's self-evident that effort put in recognizing letters should translate into significant improvement in problem solving. For example, it could be expected that this lower-level burden would drain cognitive "energy" from higher functions trying to solve the mathematical problem.
