You are conflating the typical threshold for drugs to pass random placebo controlled trials with all of academia. That demonstrates a lack of understanding and places you firmly in group 2.
It's not just drug trials, it's a huge proportion of biology and psychology research at least. Additionally, most research in biology is expensive to get off the ground, and in order to get funding it absolutely is important to project confidence - there's an entire game surrounding grant writing that sounds a lot more like "group 2" than "group 1". Group 1 is just a theoretical ideal, not the reality of academic science. While that may be somewhat field dependent it's definitely not restricted to a small niche either.
My wife's course exercises in statistics for health studies says "if the p-value is below 0.05, the relationship is statistically significant." Sure, it's a medical institution (Karolinska institutet in Sweden), but the programme she's in is about workplace health management, not even close to drugs.
Two data points do not a generalization make.
I work in engineering sciences, and we have no such threshold.
