2. Rationality Test!
• 45 seconds per
question
• Don’t cheat, that’s
irrational

3. Question 1
• Max was the president of
his secular student club in
college. He is an
outspoken teacher in
Alabama, defending the
theory of evolution
against religious parents
who push him to teach
creationism. Is he more
likely to either:
– Be a teacher of biology
– Be a teacher of biology and
not vote for Trump

4. Question 2
• If all A’s are C’s, and
all B’s are C’s, then
are all A’s also B’s?

5. Question 3
• Imagine your favorite
actor endorsing a
toothbrush. Are you
more or less likely to
buy that toothbrush?

6. Question 4
• You are offered one of
two choices: either
get $50 or 50%
chance of $110
dollars. Which do you
choose?

7. Question 5
• You are told that a
coin is fair and
observe a coin being
flipped 99 times and it
lands heads every
time. What is your
probability that it will
land heads the 100th
time?

8. We Are Not Cohesive!

9. How does our mind work?
System 1, Elephant
• AUTOPILOT
• Subconscious
• Automatic
• Habits
• Fast
• Intuitive
• Emotional
System 2, Rider
• INTENTIONAL
• Conscious
• Mindful
• Attention
• Slow
• Reasoning
• Logical

10. Cognitive Biases!

11. Retrain the Elephant and Rider
to win at life!

12. Now You Can Cheat!
• Talk to a partner
about your results for
5 minutes
• Then, we’ll discuss
the actual answers

13. Answer to 1
• Look out for the
conjunction fallacy!
All possible Maxes
are teachers of
biology. Only some
will not vote for
Trump.

14. Answer to 2
• Avoid the undistributed
middle term error!
Assign the word “human”
to letter A, and “ostriches”
to letter B. Letter C is
“two-legged.” Now it
reads, “all humans are
two-legged, all ostriches
are two-legged.” If all A’s
are B’s, then “all humans
are ostriches.” Oops!

15. Answer to 3
• Beware the Halo
effect! The Halo
effect causes us to
perceive one positive
characteristic of a
person to judge the
rest of the person’s
characteristics
positively, regardless
of the actual truth.

16. Answer to 4
• Loss aversion can
cause us to do quite
irrational things.
Imagine repeating the
exercise 100 times. If
you chose $50 each
time, you would wind
up $500 poorer on
average.

17. Answer to 5
• If you said 50%, you
might be falling into
the conformity to
authority fallacy. If an
authority figure tells
you the coin is not
loaded, but then you
observe it land heads
99 times, it’s time to
update your beliefs!

18. Think and Discuss!
• Think and write by
yourself for 5 minutes
about how these biases
might be negatively
impacting your life.
• Then, discuss this topic
with other folks around
you.
• Write down any
additional ideas you
get.
