Large language models, like humans, often display an 'addition bias,' tending to add unnecessary information rather than simplify, which can lead to less efficient problem-solving. doi.org/hbph96
Why AI may overcomplicate answers: Humans and LLMs show 'addition bias,' often choosing extra steps over subtraction
When making decisions and judgments, humans can fall into common "traps," known as cognitive biases. A cognitive bias is essentially the tendency to process information in a specific way or follow a systematic pattern.

Alterations in white matter, particularly in the corpus callosum, have been identified as a shared brain feature in both schizophrenia and bipolar disorder, supporting a psychosis spectrum model.
A common biomarker of schizophrenia and bipolar disorder revealed
For decades, schizophrenia and bipolar disorder (BD) were treated as distinct and unrelated psychiatric disorders. Schizophrenia is a psychiatric disorder characterized by altered thinking and emotional patterns, hallucinations, false or irrational beliefs (i.e., delusions), cognitive deficits, and disorganized speech.

Observing others reject unfair advantages can increase individuals’ willingness to forgo personal gain in favor of fairness, suggesting social modeling may help promote egalitarian behavior. doi.org/hbph6f
Would you take the bigger share? Study shows people can learn to say no
A new study co-authored by McGill University researchers suggests people can be taught to reject unfair advantages. "We often benefit personally from an unequal distribution of resources, a phenomenon known as advantageous inequity—for example, receiving a higher salary than a colleague with the identical role," said senior author Ross Otto, a psychology professor.
