Obviously what happened historically is that it was an evolutionary process People who were more "superstitious" and scrupulous about soaking and squeezing the cassava again and again and again lived in communities that were healthier and lived longer

People whose communities half-assed it died off They may not even have ever known that was why they died off They were just weaker and lost more people to accidents, predators, losing wars against other communities

This happened again en masse when European colonization disrupted the culture of West Africa Feeling the new economic squeeze of harsh masters demanding more work for less reward, land being cleared to grow cash crops, being ravaged by war etc, the "old ways" were forgotten

Modern science had to swoop in and try to figure out the cause and it took them a while, for all their technology and expertise It's a hard thing to nail down, the first suspects are either germs or a nutrient deficiency and it wasn't that

The actual answer, the opposite of a nutrient deficiency - an environmental toxin that's universally present in the community's staple food source - was kind of a harsh surprise

There's been a lot of papers written about the UN having to go humbly to find old women who remembered the "old ways" so they could train the younger generations on how manioc should be properly prepared It's the original case study of hidden value in "primitive folkways"

And I mean yeah In the *long* run Western science and our philosophy of asking questions and overturning tradition and inventing new things won, I suppose In the modern era you can just buy tapioca starch made from cassava in a factory with no risk of poisoning yourself

But a lot of people suffered and died in that transition The long period of time in between in which smart arrogant white people showed up and said "This whole three day soak thing is a huge waste of time and time is money so we're changing it"

It turns out that ugly cliché of "I'm just telling you how to do it because this is how my mom told me to do it and how her mom told her to do it and scores of generations that survived this long can't be wrong" isn't always a bad thing

Most people in history who survived a long time didn't do it by being clever and using their brains and figuring things out from scratch at all They survived by taking orders and doing what you're supposed to do
