Harlow's Experiments

I think that the Harlow experiments should not be repeated now or in the future because it's a form of animal cruelty. Sure, they found out that humans do have similarities with monkeys and apes, but that should be the end of the testings. If this experiment is done today, I think many people will criticise what anthologists do. The monkey in the video looked very much in pain and I think it was totally wrong for them to even think about doing this experiment.
