Laboratory Bias
Lab bias is when everything looks perfect in the lab, but real life is like a broken toy. Scientists think they're smart, but the real world is full of problems they never saw coming.
I did my lab and everything worked, but in real life, my dog ate my experiment.
The lab said the plant would grow, but outside, it was trampled by my brother.
My lab was perfect, but in real life, my teacher failed me because my dog barked.
