I really liked this informative discussion about age and mental ability. This does not address the issue of dementia but of ability to do the job as one ages.
Research shows that these capacities mainly involve decision-making skills grounded in extensive job-related knowledge, and that the types of errors made by Biden and Trump do increase with age, but that doesn’t mean either candidate is unfit for office.

In intuitive decision-making, people quickly and easily recognize a complex situation and recall an effective solution from memory. For example, physicians’ knowledge of how diseases and symptoms are causally related allows them to quickly recognize a complex set of patient symptoms as matching a familiar disease stored in memory and then recall effective treatments.
A large body of research on fields from medicine to military leadership shows that it takes years – and often decades – of effortful deliberate practice in one’s field to build up the knowledge that allows effective intuitive decisions.
In contrast to the ease and speed of intuitive decisions, the most complex decisions – often the kinds that confront a president – require conscious deliberation and mental effort at each stage of the decision-making process. These are the hallmarks of deliberative decision-making
Psychological scientists who study these topics agree that people need three key thinking dispositions – referred to as “ actively open-minded thinking” or “wise reasoning” – for effective deliberative decision-making:
In contrast, Trump has considerably less experience in politics. He claims that he can make intuitive decisions in a field where he lacks knowledge by using “common sense” and still be more accurate than knowledgeable experts. This claim contradicts the research showing that extensive job-specific experience and knowledge is necessary for intuitive decisions to be consistently effective.
My overall interpretation from everything I’ve read about this is that both candidates show aspects of good and poor decision-making. However, I believe Biden regularly displays the deliberative dispositions that characterize good decision-making, while Trump does this less often.
Biden and Trump may forget names or personal details, but here is what really matters in assessing whether they’re cognitively up for the job
I’m a cognitive psychologist who studies decision-making and causal reasoning. I argue that it’s just as important to assess candidates on the cognitive capacities that are actually required for performing a complex leadership job such as the presidency.Research shows that these capacities mainly involve decision-making skills grounded in extensive job-related knowledge, and that the types of errors made by Biden and Trump do increase with age, but that doesn’t mean either candidate is unfit for office.

Intuitive vs. deliberative decision-making
There are two types of decision-making: intuitive and deliberative.In intuitive decision-making, people quickly and easily recognize a complex situation and recall an effective solution from memory. For example, physicians’ knowledge of how diseases and symptoms are causally related allows them to quickly recognize a complex set of patient symptoms as matching a familiar disease stored in memory and then recall effective treatments.
A large body of research on fields from medicine to military leadership shows that it takes years – and often decades – of effortful deliberate practice in one’s field to build up the knowledge that allows effective intuitive decisions.
In contrast to the ease and speed of intuitive decisions, the most complex decisions – often the kinds that confront a president – require conscious deliberation and mental effort at each stage of the decision-making process. These are the hallmarks of deliberative decision-making
Psychological scientists who study these topics agree that people need three key thinking dispositions – referred to as “ actively open-minded thinking” or “wise reasoning” – for effective deliberative decision-making:
- Open-mindedness: Being open-minded means considering all of the choices and objectives relevant to a decision, even if they conflict with one’s own beliefs.
- Calibrated confidence: This is the ability to express confidence in a given forecast or choice in terms of probabilities rather than as certainties. One should have high confidence only if evidence has been weighted based on its credibility and supportive evidence outweighs opposing evidence by a large margin.
- Teamwork: This involves seeking alternative perspectives from within one’s own advisory team and from stakeholders with conflicting interests.
Applying this to the candidates
As for the 2024 presidential candidates, Biden has extensive knowledge and experience in politics from more than 44 years in political office and thoroughly investigates and discusses diverse viewpoints with his advisers before reaching a decision.In contrast, Trump has considerably less experience in politics. He claims that he can make intuitive decisions in a field where he lacks knowledge by using “common sense” and still be more accurate than knowledgeable experts. This claim contradicts the research showing that extensive job-specific experience and knowledge is necessary for intuitive decisions to be consistently effective.
My overall interpretation from everything I’ve read about this is that both candidates show aspects of good and poor decision-making. However, I believe Biden regularly displays the deliberative dispositions that characterize good decision-making, while Trump does this less often.
