It probably sounds cruel if someone tells you a particular field of study is actually not a science.
But for a study to be a science, we need a collection of things that can be proven time and again– we need reproducibility.
Does your work lead to a number? If yes, do that experiment 15 times, and then go to statistics and use those 15 data points to calculate a 95% confidence interval.
19/20 = 0.95 = 95%
You will get a result like 10 plus or minus 2 which means your 95% confidence interval is 8 to 12.
On average, 19 out of 20 experiments will give a value between 8 and 12.
I hope this is interesting, and I’d like to defend non-scientific studies. Work involving memorization of lots of facts can be valuable. The doctor who is trying to figure out what’s wrong with me, I hope that she or he has a lot of facts memorized.
