    Hi there!
    I'm a new youtuber and I make a few videos about psychology (a little bit more to fun than studying, but giving a few facts). My most recent video is about Social Influence and is inspired by this video. I would be happy if you guys could check it out! Thanks!

    The Milgram experience is severely flawed because it's impossible to gauge the extent to which the participants took it seriously or even believed they were inflicting pain. A few years back, a French TV show tried to replicate the experiment in a show called "Le jeu de la mort" ("Game of Death"). Their model was even more flawed because they used a famous celebrity and it was produced by a major network — i.e. all the ingredients that scream gimmick.

  10. The Awakening Channel says:

    It is something to admire that any human being after High school can think for themselves.

  11. Speeb says:

    The shock generator actually started at 15 volts up to 450 volts, not 30 volts

  12. Joel Varghese says:

    Social influence is something everybody experiences everyday, regardless of who they are, what they do, etc. It can have a positive or negative effect on a person's life, depending on how they react to it. Peer pressure is an example of social influence. Going against your views and beliefs to gain acceptance and approval is very common among youngsters. It has negative consequences most of the time. Most students in colleges who start drinking or smoking does it out of peer pressure. It can be overcome if you're strong in your beliefs and views, rather than succumbing to the urge of your colleagues.

    I'm gonna go out on a limb here. But something tells me all the participants in this experiment are White Christian Males.

  14. Ponk 80 says:

  23. Gadget Gadget says:

    I love everything Vanessa says and I've learned so much from her. She is amazing, smart, and awesome in everything. ALTHOUGH I think this is the first time I completely disagree with what she says.

  24. Christina Bruehler says:

    What do we do? DESTROY them.

  25. dawn says:

    the best way to overcome feelings of revenge is by using your will force and apply the opposite approach – forgiveness and you gain invincibility .

    thank you!

  27. Maria Zwiernik says:

    I love this video. It's exactly what I was looking for to show a group of students in my class why revenge is only one choice of many. Thank you!!

  28. Blood Fire Drake says:

  31. Iberian Viking says:

    I still want revenge

  32. CountBifford says:

    This video makes revenge sound completely unhealthy, but doesn't account for why it is such a universal emotion, not just among humans but many social mammals. Natural selection is pretty ruthless with behaviors that only cause problems.

    Yeah, taking revenge can cause cycles of retaliation, but turning the other cheek can also encourage chronic abuse.

  33. Sylvester Smith says:

    She is hot ???

  34. Savvy Savages says:

    I could be wrong but I think what Sinatra meant was, become successful and rub it in your enemy's face.

  35. Victor England says:

    This is easier said than done.
    I've been planning my revenge on the guy who broke my leg 8 months ago with his motorbike. Since the first day, I visualize him bleeding, feeling pain. I see his life slipping through my fingers. And I won't rest until I kill him with lots of blood. It will be gory.
    What this woman says might make sense for someone who has been wronged in a way that they can reach success. But as for me, stuck in a bed for months, with pins everywhere, immense pain, there is nothing I can do to reach success. The only thing I can think of is how I am going to torture the bastard before I finally kill him. I've been watching him from a distance, every move he makes so when the time is right, he will pay for what he did to me.
    And I will post a video response to this woman (voice only) to tell how great I feel after I drain all the blood of his body with an axe. I have it all planned, he knows I'm coming and I swear this will be biblical, just like the film law abiding citizen.

    The body does not understand the difference between an event in your mind versus a real life event. Planning revenge means you re-live the horrible moment or scenario again and again! You lose mind space and time going to the past and not planning your future. Go for success!!! nice one Vanessa 🙂

  38. Alfred Punkers says:

    I can confirm all of this from personal experience. Prolonged personal experience. Revenge almost became an addiction for me at one point, as if I developed a dependence on it to sustain myself. It was what would get me out of bed in the morning. 

    I've managed to tear myself away from that thanks to a change in environment and people… and am 10x healthier for it. Although after such a fairly long period… I still feel like "relapsing" sometimes and seriously sinking my teeth into someone. It's difficult holding back. 

    Stupid trivial things like someone pushing in a queue can trigger this feeling sometimes, although it hasn't escaped my control for over 4 years so far. I don't doubt however, that one day, it will escape my control. I'm simply that kind of person. I've always been ambitious, and there have always been people who have had a problem with that. People who think I have some "debts" or "obligations" towards them to which I never agreed. Politics, in other words. I just hope that when the shit hits the fan the next time, I'm ready for it.

  39. SurrealOfficial says:

    Loved the video, Vanessa. It's fascinating to me how some of our default behaviors are actually self-destructive, whereas the right choice is usually the more moral one.

  40. Watcher says:

    You maybe onto something there. I've focused on getting me a life rather than seething about the other people I hold animosity towards; whilst quietly wishing bad things would happen to them. It really does help personally  shifting the focus to me succeeding & enjoying life. I still have no time for these people, but it's all about me.
