What is the definition of Effectiveness Research?

Effectiveness research is like a superhero for science - it tries to find out if a new treatment, drug, or method really works in real life, not just in a lab. It's the detective work of determining if that new energy drink actually gives you superhuman energy or just makes you feel a bit more awake.

Edgy example: "After months of effectiveness research, we finally found out that 'indfulness' is just a fancy term for 'taring at a blank space for 20 minutes while pretending not to notice your cat's antics.'"
