Probable cause of alien sighting:
1. Fatigue, dream state.
2. Lying, or retelling a story of what they saw on TV.
4. An actual alien.
And here I thought most people would object to the validity of the last few variables... The first parts seemed relatively straightforward to me.
You're both technically right, but only if you take the comic's text extremely literally
. I'm 99.7% sure that Randall was trying to say...
: People who completely made up the encounter, and crazy people who thought it was real
: Sane people who honestly believe that the encounter was real
You'll that someone cannot be in both categories at the same time (which makes CR
= 0), and that the two categories cover the entire set of people who have had an "alien encounter". And as for the "probable causes of alien sightings", 1 and 3 fall under MI
(people are misinterpreting a physiological experience), 2 fits into CR
, and 4 is void in the context of this comic.
