Twins are a great resource for scientists, because you can do some crazy things to one of them and measure the effects of your experiment against the “control”—the other one. Putting aside some of the darker moments in twinstory, just take a look NASA, who used astronaut twins Scott and Mark Kelly to see how space affects the body. The following examples of twin experimentation from Reddit are decidedly less scientific and decidedly more hilarious.
1. Bakkasake's parents wanted to know what would happen if their matching set had matching names.
I have a twin Brother , Our parents decided to name us the closet as possible , our names are a letter difference and pronounced the same in certain cultures. Needless to say the experiment wasn't so secret . In High school i wasn't in the yearbook for 3 years because i was thought to be a "Duplicate" , We shared the same classes some years which allowed for some fuck ups when comes to grading. he would have never passed Algebra 2 without my grades. We now work at the same place but different departments. I get Emails from his co workers as he does mine. So Thanks Mom and Dad ,you have perfected the troll
2. Atarifan2600's running a long experiment on shirt color and personality.
3. This experiment by ChthonicIrrigation's bro-in-law had instant effects.
When my brothers-in-law were young their father told them there had been a mix up in the hospital so Fred was Dave and Dave was Fred.
A crisis of self ensued, including switching personalities until he revealed the truth.
Edit: thank you every single American telling me about 'Zack and Cody'. I'll be sure never to watch this terrible light entertainment.
4. While Oxwum10's parents organized a long-running test to see who was fastest.
5. Overthinkingmyuserid has a genius mom to compensate for his freaked out brother.
6. Norberthp proves you don't actually have to have twins to trick your kids.
7. Names. Names are crucial. As this guy knows, and disregards.
8. Yocum137's testing the effects of a flat age hierarchy.
We refuse to tell anyone who was born first because we don't want anyone, including them, to make any assumptions about them based on their age, like this one is older so she's the leader, or that one is younger so she's more laid back, etc. Not even their grandparents know.
