Hard Problem of Controlled Studies Tee
The problem of external validity (the "lab vs. world" gap). Controlled studies, especially randomized controlled trials (RCTs), are the gold standard for establishing causality. But to achieve control, you must isolate variables in an artificial, simplified environment. The hard problem is that this very act of control often strips away the real-world context, complexity, and interactions that determine how a treatment or phenomenon actually functions in the wild. What works perfectly in a double-blind RCT might fail or cause harm in a messy society because people aren't lab rats and the world isn't a sterile cage.

Great shirt. Great service. Shopify doesn’t track the shipment accurately though. However, when I reached out to Urban Dictionary customer service, they were able to help me.
Wore it to school.
Love this shirt so much
I love this t-shirt that says morbussy. It allows me to show off both my love for Morbius and the fact that I get no Morbussy.
This shirt feels great, perfect fit too.
Great looking t-shirt. Good quality. Printing looks good.
Cool I didn’t order anything I just have a lot of free time and not a lot of hobbies
Fun and soft.
Good stuff! Although, I do have a sneaking suspicion that this is cursed. You see, whenever i dawn this top-teir, soft, stylish shirt - I proceed to pass out within 46 seconds. The mere act of making contact with the material insues the process of this countdown starting. If I do not quit contact, i will lose conciousness the exact moment the countown hits 0. And when I regain clarity, I find myself in a bathtub - never mine, but a bathtub nevertheless. In the bathtub, there is always various colours of hairdye. I then have to go back home, shirt stained with dye. Very fashionable though! 10/10
Smooth transaction and nice product, shipping was quick!
