    I had a hard time watching this video and decided I couldn't watch the whole thing due to the sad aspects of it. I had learned some of these in my psychology classes and even learning about them then was hard for me to emotionally grasp. As sad as it is, this is still something that is important to learn in the field of psychology so that we don't make these mistakes again. It's a good thing that the Institutional Review Board exists so that these types of experiments can't be funded or officially conducted.

    The blue eyed/brown eyed project was told to me in my history class, when we had a lesson about discrimination. I forgot about that lol, so thank you for reminding me :') !!

    You talk about discrimination at 3:55 and then called Hitler the "toothbrush mustache man", really Psych2Go? You could literally use term, "The Austrian Painter" to avoid copystrike or something. Btw. Stalin killed 3 times more people than Hitler, bye.

    Edit: Strong racism and discrimination started when Hitler became a Führer so in 1930's. I know y'all American but do a little bit more research. Thanks.

    2, 4, 5, 6, 7 and sorta 9 to a small degree; my psych courses mentioned these experiments. 1, 3, 8, 9, 10 ive never heard of or i might have brief seen but it was barely touched upon

    Probably one of the greater moral dilemmas for me is what kinds of research should be permitted
    Which i guess is why i should be glad that choice has kinda already been made
    It's undeniable that something can be learned from almost any kind of experiments
    But it's not always known whether the subjects were okay or not with the experiment occurring and all the things that happened during it
    And quite a number of experiments depend on the subject not being aware that they're involved in it until after it all blows over

    4chan is a phycological experiment In what happens when your given 100% anonymity and a message board with no rules. And that's a good thing. I will take my freedom and all the risks that come with that.

    Haha, I'm in danger. I know I based something in my life on the marshmallow idea… But I don't know what, all I know is that I've created a habit based on a faulty study.

    The Stanford Prison Experiment had a huge flaw in its execution, the guards were specifically told to act that way even when they didn't want to, shown in leaked tapes and confessions by guards from the experiment. That fundamentally messes with the findings of the study.

    In the Milgrim study they tell us that people are capable of hurting others in monstrous ways because of authority, ive read about this in psychology. It’s because these people feel that they’re not responsible for their actions and the one who ordered them to do so is

    I feel like I would run in the movie theater test. Not because of "scary bikers" but because I get extreme anxiety in crowds at all.

    Whatever, if you can cause one human suffering to benefit all other humans do it. I don’t mean to sound cruel but one human life is nothing if it can benefit TWO humans lives. Me have a couple billion people so if I could kill 100 people to make a renewable energy source or a possibility to create mars homes or anything else that would make human life generally better I would. In 2019 141 million people were born a day. What’s a couple people if that many are born each day? If you gotta test a head transplant you might kill a guy, but you also might save millions of people and be able to create fake veins and such to create surgically connected heads like they did with dogs. Sure the dogs died afterwards but now we know it’s possible and we built on that. Two dogs died but 372960 were born that day, that could be helped more than before. You get the point by now.

    The prison experiment is null because the guards were requested to be mean to the prisoners. Not to treat them fairly. That is an influence. Also, the types of people who applied to be in the role play were not biased and not random.

    One thing that wasn't mentioned here about the Stanford Prison Experiment is that the guards actually took the prisoners' beds and clothes

    With the brainwashing technique.. I learned about subliminal songs years back and I think it make sense that your brain catches up on the words

    I remember 1 time in school we were doing this public question thing where you chose 1 or 2 publicly. I chose 1 but everyone else chose 2 I remember standing my ground and I was right. I felt so good after that. From then on I always stand my ground… Even though sometimes I was wrong.
