I'm an Economics PhD (And former professor) and if someone were to say those lines at an academic conference there is a high likelihood that they would be literally laughed at.

Maybe it is because of my background in a quantitative field where we place a huge emphasis on statistical rigor, but t-tests were pretty much dismissed by anyone serious 20+ years ago. Seems like the issue stems to those disciplines without a stats/math background to just point to t-stats. My wife reads medical literature for her work and I gag pretty close to every time she asks me to look at the results.
