i mean, you’re really burying the lead there when the article states pretty clearly in the abstract that the existence of this is contentious.

your quote doesn’t really demonstrate it doesn’t exist, it just demonstrates what the article already clearly states which is that people don’t agree.

it’s disingenuous to quote that specifically while ignoring things like:

In 2021, John Bechhoefer described a way to reliably reproduce the effect.[23] In 2024, Argelia Ortega, et al. studied the freezing of small (1-20mL) drops in a Peltier cell with a thermographic camera, and found that hot drops consistently froze faster than cold ones, with a more pronounced difference for larger drops. In particular, hot drops finished freezing sooner after the onset of recalescence, and experienced less of a temperature spike during the freezing process.[24]

from the exact same article, is all i am saying. bad rhetoric.

Modern studies using freezers with well-understood properties have observed the Mpemba effect where water supercools before freezing. Water that starts out cooler tends to reach a lower supercooled temperature before freezing.

Also from the Wikipedia article.

If you define the Mpemba effect as hot water reaching 0 degrees faster, then no, it's not observable. But if you define the Mpemba effect as heated water freezing sooner, (remembering that freezing can initiate below the "freezing point" when water is subcooled) then the Mpemba effect may be observed.

If true, it would be interesting that cool water is less likely to nucleate and form ice than water that was heated.
