[Question] Has Someone Checked The Cold-Water-In-Left-Ear Thing?

I somewhat recently read these posts, and figured this was enough evidence that it might be worth checking whether people become better calibrated for a short while after very cold water is poured in their left ear. For example: does doing that noticeably improve scores on the calibration game for a few minutes? Has this already been tested in some fashion aside from whether it changes existing strong beliefs in rationalists? If it hasn’t, a simple n=1 experiment seems fairly cheap to try, so I’ll probably go for it over the next few days.
