Anything could have enough significance to warrant further study. If it has societal implications or environmental concerns, it could be deemed worthy. I’ve read some guidelines on how to read scientific papers, but don’t have the link on me. The scientists are supposed to list their biases, but it’s kind of on the honor system, I think.
While I can concede your point that it’s feasible and possibly even more practical to open from the stem, I gotta say that since switching to the other end years ago(because I saw a similar thread on reddit), it’s been super easy and I’ve had zero issues. The stem just has a higher rate of fucking up, but it’s not like either end will fully decimate the banana. Peeling properly after it’s opened is an easy fix either way.
