7. Cognitive Dissonance
"I told someone that the task was interesting“
Vs.
"I actually found it boring."
• The $20 condition => an obvious external
justification => less dissonance
• The $1 group => no other justification.
fun
9. “This must be worthwhile
because I’ve spent time on it!
And now that I’ve kicked in
$20, it must be valuable
because only an idiot would
kick in $20 if it wasn’t!”
10. Take away message:
• When making a purchase, players know it
is unwise to spend money.
• But, they justify their purchases to help
convince themselves that they are not
foolish.
• The only solution is to keep paying to keep
playing.
11. Experiment no.3
1997 Fogg, BJ, & Nass, C.
Group No. 1 No. 2
Task 1 Answer a series of questions with the help of computers
Computers Helpful when answering
participants’ question
Unhelpful, offering unclear
answers
Task 2 Switched roles and the machines began asking the people for
assistance with their questions.
Results Performed almost twice as
much work for their machines
12. People vs. Machines
• Mutual give and take is also observed
when humans interact with machines.
• We invest in products and services for
the same reasons we put effort into our
relationships.
13. Take away message:
You have the opportunity to leverage this
central trait of human behavior –
reciprocity.
Ask for an investment in your product
after the reward.
14. Wrap-up
1. We Irrationally Value Our Efforts.
2. We Avoid Cognitive Dissonance.
3. We Give Back (Even To Machines).
