Bullshit 
Asymmetry 
Principle
The amount of energy 
necessary to refute 
bullshit is an order of 
magnitude bigger 
than to produce it
The science behind 
http://www.wpclipart.com/medical/anatomy/brain/four_lobes_of_the_cerebral_cortex.png.html
This is how we are
System 1 
Quick pattern matching 
parallel processing, unaware mode 
Low energy consumption 
System 2 
Complex elaboration that need 
attention and concentration 
No parallelism 
High energy consumption
Some battles cannot 
be won
Information asymmetry 
position asymmetry 
time availability
Avoid them 
Don’t put key people in the position to bullshit you
Create context 
Environment, fail-safe condition, confidence…
Accept it 
Somebody is always going to be wrong on the internet
