I can tell from watching the first five minutes of the video that a) Gershoff is trying to refute a rather simplistic view of corporal punishment applied by parents with no insight into the human condition, nor their children’s individual personalities. b) Her use of “weasel” words such as “linked” to tie together both strong and weak conclusions makes her more advocate that researcher.
Indeed. reminds me of some Climate Change cooking. Based upon her conclusions, saints of the Bible, as well as those born before 1950 where (I have read) 99% parents spanked, then they should have been the most mal- adjusted children, with frustrated parents. And instead now we have touchy-feely snowflakes who demand all that offends them be shut down. Which ultimately means using the power of the state, which ultimately is physical.
