Scientific research...rrriiiggghhhhhttt...done by psychology majors with an agenda to push. Are there kids out there who didn't need corporal punishment? Yes. Are they the majority? No. Sorry, there are more brats out there than decent kids due to the lackadaisical idiots who don't actually parent, and they try to claim "scientific research" which is liberal speak for "how to push not doing your job as a parent because you're an idiot"
