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...
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

Bullshit Asymmetry Principle lightning talk

  1. 1. You’ll never win against… B.A.P.
  2. 2. “I gave you 2 more persons... You’ll deliver earlier!”
  3. 3. “I gave you 2 more persons... You’ll deliver earlier!” - Linear outcome (false) - Linear proportion between cost and delivered value (false) - Linear starting costs (false)
  4. 4. “We couldn’t hire a senior, so we hired two juniors”
  5. 5. “We couldn’t hire a senior, so we hired two juniors” - Linear outcome (false) - Linear proportion between cost and delivered value (false) - Linear starting costs (false)
  6. 6. “Proceed with the other activities in the meanwhile”
  7. 7. “Proceed with the other activities in the meanwhile” - Null context switch cost (false) - Suspended activities remain idle (false) - Doing is always better than not doing (false)
  8. 8. B.A.P.
  9. 9. Bullshit Asymmetry Principle
  10. 10. The amount of energy necessary to refute bullshit is an order of magnitude bigger than to produce it

  12. 12. This is how we are
  13. 13. 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
  14. 14. Some battles cannot be won
  15. 15. Information asymmetry position asymmetry time availability
  16. 16. Avoid them Don’t put key people in the position to bullshit you
