A 2015 project attempted to replicate 100 psychology studies. Only 36% of the original results held up. Those original studies were published in top journals, but they failed the test of complete science because nobody could get the same answer twice.
Often used interchangeably with "rocket science," this implies a task is simple. completely science
For over two millennia, atoms were a philosophical guess. Democritus proposed them in 400 BCE, but there was zero evidence. Was that “science”? No—it was metaphysics. A 2015 project attempted to replicate 100 psychology studies
The leap to completely science occurred in the early 20th century: Today, atomic theory is completely science
Today, atomic theory is completely science. Every prediction—from chemical bonding to nuclear fission—fits the evidence. No major scientific body disputes the existence of atoms. That is the gold standard.
The now-retracted 1998 Wakefield paper linking MMR vaccine to autism was not completely science—it had a sample size of 12, no control group, and undisclosed conflicts of interest. Real science requires thousands of subjects, blinding, and replication. Subsequent studies on millions of children found zero link, making the original claim unscientific.
Key takeaway: Using the word “science” does not make something completely science. Just as “vegan” on a label doesn’t prove a food is healthy, “science-backed” requires scrutiny.
