A new test of cephalopod smarts has reinforced how important it is for us humans to not underestimate animal intelligence.
Cuttlefish have been put to a new version of the marshmallow test, and the results appear to demonstrate that there’s more going on in their strange little brains than we knew.
Their ability to learn and adapt, the researchers said, could have evolved to give cuttlefish an edge in the cutthroat eat-or-be-eaten marine world they live in.
The marshmallow test, or Stanford marshmallow experiment, is pretty straightforward. A child is placed in a room with a marshmallow. They are told if they can manage not to eat the marshmallow for 15 minutes, they’ll get a second marshmallow, and be allowed to eat both.
This ability to delay gratification demonstrates cognitive abilities such as future planning, and it was originally conducted to study how human cognition develops; specifically, at what age a human is smart enough to delay gratification if it means a better outcome later.
Because it’s so simple, it can be adjusted for animals. Obviously you can’t tell an animal they’ll get a better reward if they wait, but you can train them to understand that better food is coming if they don’t eat the food in front of them straight away.
Last year, cuttlefish also passed a version of the marshmallow test. Scientists showed that common cuttlefish (Sepia officinalis) can refrain from eating a meal of crab meat in the morning once they have learnt dinner will be something they like much better – shrimp.

A University of Cincinnati graduate assistant wrote that “intelligence is a White man’s mythology.”
“Stop calling your female colleagues ‘smart,’ or ‘clever,’ or ‘brilliant,’” wrote Mel Andrews, who studies cognition and evolution. “It’s sexist and infantilising… it shouldn’t be surprising to you in 2021 that women are capable of thought.”
“You’re doing the same thing when you describe your Black and Latino students as ‘very bright,’” added Andrews.
“Intelligence is a White man’s mythology. A phantasmal concept. A non-referring term. Syncategorematic,” she wrote.
Indicating that her post was entirely serious, Andrews posted an excerpt from a chapter that she wrote for a book entitled Handbook of Parenting. She cited works claiming that “more than a century of wanton reductionism and definitional vagueness in the study of intelligence and human potential has perpetuated a stratified social order and obscured the true dynamic complexity and diversity of human cognitive development.”
“Intelligence is the capacity to receive, decode and transmit information. Stupidity is the blockage of this process. Bigotry, ideologies etc. block the ability to receive; rigid reality-tunnels block the ability to decode; censorship blocks transmission.”Robert Anton Wilson
“The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence.”Charles Bukowski
