It’s fine to not understand how university research works… All the protocols, checks and balances, and etc that are in place to ensure it’s validity. But when you post this sort of nonsense on the Internet, you really only embarrass yourself.
If we get into the test protocols, and how these originally came out when MIPS was being introduced, there are simply in my mind, more questions than answers.
MIPS' selling point, is primarily I believe based on reducing concussion incidence from rotational impacts, with the MIPS liner providing some rotation give that can prevent that. However, then why have a test protocol that eliminates all of the pre-existing mitigators of rotational impact when testing a helmet, such as:
1. Humans (most) have hair.. this moves
2. Humans have necks, the heads on top of them bend and rotate
3. Humans have a scalp/skin -- which slides a bit over the cranium underneath
4. Humans often wear helmet liners or thermal caps for sun protection and/or insulation in cold weather.
Rather, the test protocol is strapping a helmet strongly to a somewhat tacky, hard, and bald immovable head form. Given that Va Tech at least for other sports, seems to actually test those helmets with bendable neck forms, this seems very strange. With VaTech's test methodology, it does support MIPS, as it MIPS does introduce a slip plane to a test object that has none of the normally naturally-occurring ones that aleady exist.
