Anyone else get acquainted with tontine from the simpsons? I watched that episode as a kid and still remember it to this day.

No, The Butt by Will Self.

I've always known the parachute manufacturers mostly ride on fear, uncertainty and doubt on this. They ruthlessly cash in on people's lack of knowledge and fear of death, advertising parachutes as a safer option which people buy because it's like insurance; if you'd happen to fall, you'd at least want to feel having prepared.

So I'm glad to hear there's now some scientific evidence pointing to the futility of parachutes. Surely, the experiments were carried out in a constrained environment with some unavoidable assumptions baked in but it does rather convincingly suggest that parachutes consistently do not offer any help in the event of freefall.

A corollary might appear that parachutes might even do more harm, adding weight to the falling person which could cause further injuries unnecessarily upon touchdown.

I'll look forward to follow-up research.

The big question is how would altitude affect the results.

For experiments at higher altitudes they might need to locate an airstrip situated on a mountain, with enough runway to allow larger planes to land there and enough free space on the tarmac for several planes while they carry out the jumps. It will likely shed much more light and build confidence to the applicability of this new research and the obvious conclusion.

Also, I'd like to see jumps done from different kinds of aeronautic vehicles, by more people, different brands of parachutes etc if should there be any differences regarding that. But it looks like after a few rounds of serious experiments we should quickly conclude the benefits are thin and see no need for excess research but, rather, reaching a steady conclusion.

There's a short term group loaning 'game' in Cambodia called and based on Tontine, which I would guess comes from the French influence. The game is played by groups who agree on a monthly stake. Each month players offer an interest rate they're willing to pay (more like a tax), the highest rate is awarded the collective pot, less the interest which is redistributed to the other 'living' players. Players who have alre…

Maybe I'm misunderstanding, but how is this different than a pyramid scheme?

From my understanding, there's nobody added on while it is running, but a fixed group from start to finish.

That's awesome, thanks! So is this: https://tontine.com/

Still popular in France, in 1906 they fell out of favour in the US due to the insurance company issuers tampering with the membership ledgers & then withdrawing too much investor capital as "insurer profits".

Some things never change.

How is it prevented that they get "stuck" because no participant needs the money right now and would rather wait and see if someone else is willing to pay an interest?

A coworker of mine once made this proposal. 5 of us would start a company. The company would buy key man insurance for everyone, then go on a company team building trip. On this trip, we'd all skydive, but one of the 5 parachutes would be non-functional...Profit! This coworker of mine soon after left the company by storming out of the meeting room and slamming the door, then took up playing online poker for a living.

My first introduction to this concept was through the wonderful https://www.imdb.com/title/tt0061204/ (The Wrong Box). Highly recommended.

Remember to reard the linked editorial for context: https://blogs.bmj.com/bmj/2018/12/13/we-jumped-from-planes-w... > We conducted the PARACHUTE trial to illustrate the perils of interpreting trials outside of context. When strong beliefs about the standard of care exist in the community, often only low risk patients are enrolled in a trial, which can unsalvageably bias the results, akin to jumping from an aircraft w…

It's also essential to read the first cited article ( https://www.bmj.com/content/327/7429/1459?ijkey=3b8c1a70a8d2... ) which very much inspired this paper and is also quite a bit funnier.

> The relevance to parachute use is that individuals jumping from aircraft without the help of a parachute are likely to have a high prevalence of pre-existing psychiatric morbidity. Individuals who use parachutes are likely to have less psychiatric morbidity and may also differ in key demographic factors, such as income and cigarette use. It follows, therefore, that the apparent protective effect of parachutes may be merely an example of the “healthy cohort” effect.

I suspect that landing on water has no discernible effect on the health of the suspect. And he will be completely soaked, so avoid jumping over water and always try to land on land.

It would be pretty interesting to make an Ethereum based Tontine system
