(To be clear, I don't think that will actually happen, but it would be hilarious if it did!)
Let:
A = amount of ethanol
V = initial whiskey volume
W = added water
Initial concentration: c₁ = A / V
After dilution: c₂ = A / (V + W)
If you drink the entire diluted glass: ethanol consumed = c₂(V + W) = A
Intoxication ∝ ethanol consumed
Therefore: drunkenness ∝ A not ∝ (V + W)
Adding water changes concentration, not the total ethanol: A = constant ⇒ drunkenness = constant (ignoring effects of drinking rate).
Saying that “less diluted works better” is saying the diametric opposite of what Homeopathic “theory” does!
Homeopathy was invented after the discovery of germ theory [1][2]. So not really. And homeopathy has always suffered from an adulteration problem.
Homeopathy was created in 1796, and we still haven’t gotten rid of it.
Meanwhile 65 years later https://en.wikipedia.org/wiki/Ignaz_Semmelweis
The maternal mortality rate dropped from 18% to less than 2%, and he published a book of his findings, Etiology, Concept and Prophylaxis of Childbed Fever, in 1861.
Germ Theory was only finally accepted (after initially being rejected) due to the advent of evidence-based medicine, which homeopathy popularized.
A lot of doctors are shoving people out the door based on their first thought inside a short appointment as they type up a prescription.
Homeopathy is ineffective kookery, but our medical system has some well known gaps.
But what are the incentives of those who did those tests? That should be said in the same breath as you say "empirical testing/evidence".
Despite the "consensus" thoroughly "debunking" it conclusively many times...
Also, if it ever happens, I think it would be during course of many decades that all the existing "scientists" can save their faces, and new generations won't care about "Science" being wrong once again, despite all the projections of "certainity" back then..
