Whales and dolphins lead 'human-like lives' thanks to big brains, says study
[In] a new study, researchers compiled a list of the rich behaviours spotted in 90 different species of dolphins, whales and porpoises, and found that the bigger the species' brain, the more complex – indeed, the more "human-like" – their lives are likely to be.
This suggests that the "cultural brain hypothesis" – the theory that suggests our intelligence developed as a way of coping with large and complex social groups – may apply to whales and dolphins, as well as humans.
Writing in the journal, Nature Ecology and Evolution [DOI: 10.1038/s41559-017-0336-y] [DX], the researchers claim that complex social and cultural characteristics, such as hunting together, developing regional dialects and learning from observation, are linked to the expansion of the animals' brains – a process known as encephalisation.
The researchers gathered records of dolphins playing with humpback whales, helping fishermen with their catches, and even producing signature whistles for dolphins that are absent – suggesting the animals may even gossip. Another common behaviour was adult animals raising unrelated young. "There is the saying that 'it takes a village to raise a child' [and that] seems to be true for both whales and humans," said Michael Muthukrishna, an economic psychologist and co-author on the study at the London School of Economics.

So, why are the rest of the apes so damn stupid compared to humans?
Some have suggested that experimentation with psychedelic mushrooms is responsible for an extremely rapid and large expansion of the human brain, as detailed by the fossil record and by cave art, and by the oral stories that form the foundation of most religions around the world.
Give them dolphins some shrooms!.. in the name of science.

Dolphins eat fugu fish, the puffer fish loaded with tetrodotoxin, to get high. Somehow, that works for them.

The only problem is authoritarianism.
Without authoritarianism:
laws are simply contractual obligations to which each individual has voluntarily agreed.
religions are simply personal philosophies by which individuals choose to live their lives as meaningfully as possible.
money is simply a logistical technology that enables complex cooperation, placing ever more control over society's resources into the hands of those who prove to be good stewards, and removing ever more control over society's resources from the hands of those who prove to be bad stewards.

Your point is? The human world has been built, run, and dominated by gangs since it's beginning, that is the normal course of things. People SHOULD look out for themselves and their neighbors and defend each other from external aggression, and when it comes time to be the aggressor, better have a team behind you. Humans are not a species that lives individually.

Nobody is saying the parents should abrogate all responsibility to the community, just that the parents and immediate family alone aren't enough to teach a child about how to function in society: How to behave with strangers, how to differentiate friends from foes, how (and when) to properly assert oneself / negotiate / compromise, how much trust it is appropriate to put in different people... These things require direct lessons and experience that can only be perfected by interacting with a range of children and adults of varying levels of familiarity.

“For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much—the wheel, New York, wars and so on—whilst all the dolphins had ever done was muck about in the water having a good time. But conversely, the dolphins had always believed that they were far more intelligent than man—for precisely the same reasons.”

Dogs and cats (and their wild counterparts) do this too, and they have tiny brains. Many bird species as well, with even smaller brains. Is it brain size or just a symptom of how the underlying hardware works? I'd find it far more plausible that problem solving and number crunching are benefited by larger brains rather than socializing, which is seen in nearly every social animal (which is most of them except for the largest predators).

Brain size is almost meaningless. The brain to mass ratio is the metric that correlate the best with problèms solving skills. Using that metric, birds fit were they belong ostrich(the stupidest bird not extinct) included...
