I have not been able to find out how long these effects lasted, or if there was any follow-up beyond the initial questionnaire.
If there were any lasting effects, the experiment was unethical.
The effects were temporary, and probably dissipated as soon as the magnetic field was shut off.
I am not certain that anything can be said about this experiment beyond the fact that temporarily disengaging parts of the brain makes people think/act differently. Beyond that, to make some generalized conclusion about human behavior is to go way beyond what the evidence shows.
