I always used to think it would be a great impulsivity test to have people use an internet connection that's been 'fixed' to lag at different rates. You can then measure the number of times they hit refresh or swear as a measure of impulsivity. God knows it's probably just as valid as some of the measures we used to use in the lab.
I wonder how many times I'll have to hit refresh after timeouts to get this entry to go through.
Note: 6 Times
