Disgust Data, Round 2

I really need to find or make a questionnaire measuring specifically moral disgust, as only 2 of the items on this one could conceivably be read as moral (the two with the highest ratings--bestiality and incest; though incest is harder to explain).

Sample size: 15.
Highest score: 22
Lowest score: 4.
Average 13.

Part I
(Number who said they were disgusted by the thing described.)
(1.) 4 messy food
(2.) 12 cockroaches
(3.) 7 phlegm
(4.) 14 bestiality
(5.) 3 preserved hand
(6.) 3 walking through graveyard
(7.) 2 public toilet seats
(8.) 11 soup stirred with washed flyswatter
(9.) 4 monkey meat
(10.) 5 rat
(11.) 9 vomit
(12.) 3 gayness
(13) 7 glass eye removal
(14.) 3 touching dead body
(15.) 7 sick cook
(16.) 7 death in hotel room you’re staying in

Total possible: 15.

Part II
(Total disgustingness points--0-2--for each, summed)
(17.) 13 ketchup in ice cream
(18.) 18 maggots
(19.) 11 pee smell
(20.) 16 30/80 relationship
(21.) 4 fishing hook in finger
(22.) 12 picking up dead cat
(23.) 2 unintentional drink sharing
(24.) 4 poo-shaped chocolate
(25.) 18 spoiled milk
(26.) 13 stepping on worm
(27.) 19 unflushed public toilet
(28.) 28 incest
(29.) 15 seeing exposed intestines
(30.) 7 touching someone’s ashes
(31.) 23 infrequently changed underwear
(32.) 6 blowing up condom

Total possible: 30

Sleeping with old people: just slightly less disgusting than maggots. Brilliant.

I continue to not understand the high ratings for #31. Cannot get myself to care how often anyone else changes their underwear.
