TEDxCanberra - Ash Donaldson - Cognitive dissonance

[dij7878]

This was awesome! I was looking for something to help me explain cognitive dissonance in my Social Psychology class. This is presentation is perfect. Thanks for posting it :-)

[Greensparrow101]

His cognitive dissonance was induced by fear and lack of trust. I too, was a pilot and did instrument training, and did not have this problem. I did however... before flying. Had the "pleasure" of jumping out of aircraft at 500ft. This had two effects. I learned to trust my equipment, and had the living fear "beaten" out of me. It's a big factor in accepting reality. I wish he would have mentioned that in his speech. Still good though... nice job.

@Greensparrow101 This reality its whats detroying the mind and this world. Doesn't matter how hard may the decision be between acceping or denying it, if your mind stays strong the brain will be smart enough to learn live and make a change for the better good, outside this reality.

[Trickndel]

The people arguing "Oh he is just a pilot". Get out of your ad hominem asses and look at his reasoning. There is no one more prone to cognitive dissonance and propaganda than you. Reason being: Your logic is fallacious. In other words, you are slightly brain damaged.

[TheVariableConstant]

@Trickndel Maybe you should read more than you assume. I clarified the problem and only used what you think was an ad hominem, as a final seal to my point and not the entire bases of my train of thought. I have no interest in arguing over this, especially with someone who can't correctly read and understand as your main argument was only a fraction of my comment.

This talk needs to go on the main TED channel. Thumbs up if you agree

[NymphetamineGirl777]

Everyone should watch this talk.

[TheVariableConstant]

18:50 "and trust my instruments". The machines are winning!

Nice talk all in all but this video is extremely ironic. Having a pilot discuss physiology is like having a lawyer discuss auto-mobile assembly. His arguments are based on flawed premises.

The human eye does not pick up "pieces" of information and fill the space, this is a scienticif fact which i knew before med school. He needs to do his homework properly before spreading disinformation/ignorance.

[TheVariableConstant]

@TheVariableConstant We see everything, it is the conscious mind which is lagging and filters out information, it is responsible for things like intellectual perception, savants with less of this are able to reproduce exact replicas of seen objects even for brief moments of exposure, not because they have special organs.

It's more complicated than i care to correct not just the bit on sight but other things he mentioned.

Seems he never won his battle on cognitive dissonance after all...

[pixelprotagonist]

@TheVariableConstant For the task of detecting an aircraft, the impression that we see the whole sky clearly is a cognitive construct - an illusion to provide a seamless model of reality. There are 2 major forms of eye movement: Smooth Tracking (pursuit) and Saccadic Movement (focus). Due to the almost imperceptible movement of aircraft at a distance, detection generally requires the small focus of the fovea to land on the target - a fixation from saccadic movement.

[pixelprotagonist]

@TheVariableConstant Thanks for exploring this further.

A couple of points of clarification:

1. I'm a Human Factors Engineer (I was a commercial pilot when I was younger). We look at the capabilities and limitations of human perception, cognition, behaviour and physiology, then design systems that 'fit' the human operator.

2. As you've correctly pointed out, with only 18 minutes, I didn't have time to explain visual perception in depth.

[TheVariableConstant]

@pixelprotagonist Interesting addition.There is indeed more going on than talked about here within the limited time frame. I just didn't find it appropriate for such a complex topic as cognitive dissonance to be discussed in such a superficial manner (especially being a topic which i can relate to due to my peculiar situation)...then again, could have been the right approach under the given circumstances...maybe, maybe not.

[Th0usandMaster]

this guy got a phd on psychology or something?

[MisterCommentCritic]

@Th0usandMaster He's a Human Factors Engineer. Most of what he said is commonly accepted, he just says it in a way that is more easy to understand.

[Th0usandMaster]

@MisterCommentCritic I meant that as a compliment....

[robertplant634]

Not because Bush is evil? That one made me laugh.

[pixelprotagonist]

@hercarebear2 It's actually a 'Placebo Band' by Skeptic Bros - a $2 parody of the PowerBalance (made from the same materials most likely in the same factory)

[cutes22]

That talk kicked ass.

[Anteaterdance]

"teach kids how the brain really works. They'll appreciate science more." This is SOO true! I never had a teacher explain science as a way to overcome our natural biases. (which is such a key idea imo!) Thanks for sharing this. One of my Favorite TED talks!

[undertehlaw]

With the blast shield down, I can't even see. How am I supposed to fight?

[sjshapir]

A very nice summary with excellent examples.

I wish it were easier to get people to understand their thinking process. (Me being one of those people.)

[ageofdeception]

What a wonderful talk! Thank you!
