    Not really correct what you are saying. The brain can use ketons as a much better source of energy than glucose.

    This is a lack of sharing information. if more scientist registers would share information and challenging things we would be better off. we are just finding out Darwin was an egotistical nuthouse. I loved this video. I love information.

    I think willpower is more individual to a persons brain. They should have tried using people with depression/anxiety/severe laziness compered to athletic and healthy people with a “good” mentality

    Dopamine. Dopamine is the will power resource. I don't know why that isn't more obvious. Dopamine drives us to perform because we receive a reward upon completion. Those with drug addiction have damaged dopamine systems, and therefore can only receive a reward when using drugs. Not receiving cookies when presented with them would reduce available dopamine and have a depressive effect. Tasting lemonade would increase available dopamine. Adderall increase available dopamine and drives you to perform. Serotonin is the learning resource, and dopamine is the will power resource. Why is this even an issue??

    The thing is, dear SciShow, that Psychology IS NOT science. Science shouldn't be defined by the method of study, but by the object under study. The only sciences are those physical, exact and natural, because they center on physical laws. Human are flawled, we don't even know what the mind is. Stop trying to discover laws of behaviour based on such a limited sample.

    When your muscles ache its often due to a lack of carbohydrates...simply placing a piece of bread of potato in your mouth is enough to solve this...1. This implies we can taste more than we think ie tasting non sweet sugars. 2. This also could mean that will power is real but doesn't require physically replenishing. We don't understand how our body works fully especially our brains...for all we know not eating the cookies and not eating made them feel meh... if i hadn't eaten all day for a test i wouldn't be in the mood to focus. I'd be clucking for a subway.

    Of course, no self respecting scientist should be attempting to their own repo studies to prove the effect is real but to find out whether or not it's real.

    Good less of this nonsense is better.

    Lmao an entire psychology area for me?

    It's a new field. it'll go through some changes

    As a psychology major here is a quote from my published/practicing/intelligent professor (with a doctorate)- “The most overstudied population in psychological history are undergraduate psych students”

    They should do ego depletion with people on keto, offering them a sugar free stevia sweetened keto cookie

  • Jacky - 2 weeks ago

    I think it's more about frustration build up, not ego depletion

    Should've just stuck with the unchanging word of God...

    I have a degree in Biochemistry and one in counseling; let's just say if chemists and physicists do "science" the way it's done in the social science fields we would still be ride horse and buggy. They don't study causation but they try to infer it from correlation studies. That's where the failure is at, when they get a high correlation they conclude that it's the cause without ever being able to recreate or create the cause-effect event.

    If you have an 'impossible to solve' puzzle and someone says it can't be solved. Have they solved it?

    So willpower is dependent on keeping the brain well fed.

  • Bob Lawblawblaw - 2 weeks ago

    Psychology, even more than history, is more or less bunk it seems. Imagine my surprise.

  • Shea Sollars - 2 weeks ago

    There are too many different factors to consider. What about morality and IQ?

  • Rose M Neu - 2 weeks ago

    I don't know. When I do a task that I hate and requires lots of energy out of me, I really don't have patience/will to do another right after AND I tend to want something sweet. Oh well :)

  • truthtoknow - 2 weeks ago

    My theory is that willpower is only important in people who haven't internalized the goal. If you realize that you actually want to do x and not y, doing the right thing won't feel like a sacrifice, even if it is unpleasant. If you're forcing yourself to do something you don't want to or you think you don't want to, only then is willpower going to matter. In that case, however, you are guaranteed to fail, the question only is to when.

    WAIT I have a question. By this metric, a brain using up more glucose resources, would usually be an intelligent person, right? Then... why is obesity linked to lower levels of education and poor impulse control, rather than those who use more self-control/more glucose reserves?

  • Almog gg - 2 weeks ago

    People who lose a lot of weigh and maintain a healthy life style ant their weight for a long time have a lot of will power and self control, and it seems that the more they stick to their way of life they are more motivated.

  • Aella Lee - 3 weeks ago

    Is psychology a science or philosophy? Does it need to be more scientific? This is something we are covering in my class.

  • Sean Varner - 3 weeks ago

    eating cookies gives you a rush of energy

  • vshowers37 - 3 weeks ago

    What you failed to mention is that reproducibility is a problem that impacts ALL scientific research, not just psychology.

  • a d - 3 weeks ago

    Isnt there a reproduction problem with psych studies

  • Ziv Klein - 3 weeks ago

    How the hell is the task on the replication study suppose to be depleting? yeah it's an annoying task that requires some effort, but it doesn't involve resisting any temptations or exercising self control. it's completely irrelevent. this is also baumeister's critisism of this study. seems like this replication study just showed us that mildly difficult mental tasks do not deplete your ego, but said nothing about resisting temptations which is the whole point of the theory.

  • Spooky Boyy - 4 weeks ago

    One failed replication should be enough If it isn’t, we aren’t actually talking about science at all

  • TheWisherable - 4 weeks ago

    4:56 So watching this video and learning bout those researches has potential to deplete people of their will power..? What kinda sorcery is this.
