  1. I wonder if people higher in trait openness are less susceptible to anchoring. Ooh, what about agreeableness? Could actually test that.

  2. Ah you got me, when you first presented the problem I knew it was a trick question so I started doing some math in reverse from 1 towards 8.

    And thought exactly 512 or maybe 502 not sure anymore.

    But this question had a double twist .

  3. if we can control our urge to guess we can fix the anchor problem… simply refuse to guess… find the answer.

  4. amei do seu canal se possível dar um olhada no meu canal se inscreve, que eu retribuo o favor, valeu um abraço

  5. The first example is ridiculous. 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 is an arithmetic problem with an exact answer; there is no need to guess.

  6. Great content, but the audio has a harsh quality to it. Like maybe there's too much noise or data compression? Anybody know what it is?

  7. Being a lazy sod, I grouped the numbers, and rounded to make them easy to multiply. (2×5) x (7*3) * (4*6) * 8 is about 10 x 20 x 25 x 8 is about 200 x 200 is about 40000.

    I do get what you mean by anchoring, though. Every mattress store in my town is having a continuous 70% off clearance sale.

  8. i don't really hear voices they affect me telepathically or message wise — my thing i can not get the past outta my head like i feel my step mothers relative r sitting in a switch board and control my mind i don't really hear what they say but nonetheless their messages r clear they usually humiliate laugh at me it is like a security camera in my head controlling my thoughts also when i am on the street i feel i am brain wired to every one else and that others r thinking about me controlling me and hate me every body is in my head i can not get them at at night i feel ego shattered like even walking down a street even some one looking at me coldly this leaves me crushed and shattered –i misunderstand and misjudge every thing and can never decode or process information or behavior same with language i –also i don't know who i am like i feel i don't exit i am an ego conscious version of my step mothers relatives i feel i have died and now i am just a hologram i don't feel real or alive i feel i am divided my identity compromised of many many people when i look at a thing i feel those people in my head r looking at this thing with me–i wonder the person talking to me can see those guys in my head most the time i think they do i feel they have a packt to fuck me up i feel the whole universe and god hates me i feel so evil worthless and bad worthy of death i feel i am a worthless bug not human at all –am i schizophrenic ???

  9. want to talk about societally induced conditioning, I notice how this guy mocks 2 different Christian faiths, yet doesn't touch Islam, or Judaism, or any other religion where mockery is frowned upon…total LEFTIST DRIVEL …I myself am not religious, but I think this guy is definitely picking easy targets, and completely discredits his self… Not that it matters, just kind of helps me evaluate the inherent prejudicial nature of all religiously centered cultures….We live in an age where one group perceived as a disadvantaged minority is subconsciously permitted to slight and undermine the faith of another when they see as being tolerated by the standards set by society….SO THIS GUY BAD MOUTHING Mormons and Catholics is assuredly of no impartial scientific mind and is just another youtube fraud and quack, and if he really does have a legitimate degree which I am highly dubious of….then it certainly reflects the imminent peril of our flawed educational system, that permits allows Marxist rhetoric to parade as science….psychology this is not. Good day. 🙂

  10. Very, very interesting video.
    I was used to refer to the "confirmation bias" as a logical fallacy called "loaded question": the answer is "loaded" into the question itself, like the sentence you proposed does.
    Perhaps the confirmation bias is a kind of this logical fallacy, at least I think so. Do you?

    A brief research about logical fallacies will explain what I mean, since I do not want to make advertisements 🙂

    Kind regards from the best place in the whole world you can live, Friuli-Venezia Giulia (but only the eastern part, on the border with Slovenia 😉 ) !

  11. but aren't you biased on giving all these ideas only from your point of perspective or view? I'm a big fan of your works tho!

  12. great video ..but the first idea you explained isnt cognetive ease , its called substitution bias and both are not the same

  13. You hit the nail on the head with this one. Being a convert to the LDS church I have already been doing what you suggested about researching all sides, but the fact that you have come to a different conclusion then I doesn't mean I'm going to dislike the video or even stop listening to what you have to say throughout the others. I bet there is a massive amount of things we would disagree on. At the same time though the reason I am watching them is because we agree on a ton of thoughts and ideas as well. More people need to learn to come to their own conclusions instead of copying and pasting what others tell them. I really enjoy your videos and I watch a new one right when I wake up to start my day. Keep up the hard work.

  14. Just came across this video- Great info- I will watch them all- thanks for the work and effort.

  15. On point, I tell my girlfriend often that the more knowledge you acquire and understand, the better you'll be able to discern what reality truly is. Your view of reality will be broader. I want to know as much as possible about the reality I exist in.
