Mice Feel the Pang of Regret

Regret is the recognition that one made a mistake and that an alternative action was possible. Regret requires consideration of what might have been, aka "counterfactual reasoning". In a phrase: coulda, shoulda, didn't.

Healthcare Spending, US versus Other Developed Countries, Part VII: Recommendations

…3. Increase federal and state budgets for the detection and prosecution of fraudulent medical billing, such as upcoding. 4. Greatly expand the number of nurse practitioners working as  "full practice" primary care providers and gatekeepers, a status that allows them to work independently of a physician's clinical oversight. 5. Institute a no-fault medical malpractice system, much like the very successful one in Denmark. …

Healthcare Spending, US versus Other Developed Countries, Part VI: What Japan Can Teach US

Take MRI scans, which cost about $1500 in the US. In Japan,  the fixed price for an MRI scan is around $100 (depending on body part). Now you'd think that Japanese doctors wouldn't do that many MRIs because they couldn't make any money off them. But no - just the opposite: Japan leads the world in MRIs. What happened is that Japanese doctors asked MRI manufacturers to develop an inexpensive MRI scanner. And they got a cheap machine so they can do cheap MRI scans and still make a little profit. Sometimes the heavy hand of regulation can be a spur to innovation. …I say this as a lover of capitalism, for whom the word "corporate" elicits a sigh of gratitude.

Healthcare Spending, US versus Other Developed Countries, Part V: Administrative Costs

Between the government and private insurers, medical office personnel spend an inordinate amount of time processing bills. What is reimbursable, what is not? What type of documentation is required? What billing code should we use? How much can we charge? And that is one big reason the US spends so much on healthcare administration. Time is money.

Healthcare Spending, US versus Other Developed Countries, Part III: Drugs

Last post was about outpatient services, specifically how reimbursement rates and physician profit-sharing arrangements contribute to the cost of outpatient care in the US. This post will address the cost of pharmaceuticals…A recent JAMA study ( Papanicolas et al, 2018) found that annual per capita spending on pharmaceuticals in the US was $1443, compared to an average of $680 for ten other developed countries.

Healthcare Spending, US versus Other Developed Countries, Part II: Follow the Money

…Thus, if you want to understand why these procedures cost so much, follow the reimbursement rates. For instance, in 1997 Medicare raised reimbursement rates in certain parts of the country. On average, areas with a 2 percent increase in payment rates experienced a 3 percent increase in care provision. Physicians charge what they can, and then some.

Healthcare Spending, US versus Other Developed Countries, Part I; What Can We Learn?

Given that old people consume way more healthcare than anyone else, why do other rich countries spend so much less on healthcare than the US, when the US has comparatively fewer oldsters? Something is very wrong with this picture. What is all that money going?  … A lot is paying for outpatient care and administration, which alone account for half of US healthcare expenditures

Do Rats Have Free Will?

In other words,  rats make choices based on what they want and what they consider possible.  They imagine the future, weigh the relative merit of different actions, seek additional information if needed, choose what to do, and then act. They are agents with desires and goals.

Psychology and Politics, Part II: Truth and Research Agendas

There's something about psychologizing that's invalidating. As if psychology was the science of human error. But does it have to be so?  Humans are pretty good at tracking reality, thanks to biases and heuristics that work well most of the time. Error can be an ally in the search for truth.

Social Science and Political Agendas, Part II

Point is, no one has an emotional reaction to inequality without a sense of what it speaks to.  Inequality is a concept for God's sake. It's not at the same level of concreteness as, say, a snake slithering in the grass.

Social Science and Political Agendas, Part I

The above game is an example of what I call an "Act of God" study design, in which researchers (playing God) randomly dole out good and bad fortune to study participants, typically in the form of monetary payments.

As Simulation Machines, We Don't Have to be Rational

Prone to anxiety? The machinery will tilt towards the threat potential in its representations, systematically reviewing the possibilities. Confident and optimistic? The machinery will tilt towards images of success and triumph, but not dwell on them because no preparation is required for what may come. We already know we can handle whatever is thrown our way, and it will be good.

Please, Reality: Don't Make a Fool of Me!

On second thought, all research is desire-driven. Because behavior is necessarily goal-driven and you don't have goals without wanting something to happen and wanting is desire and doing science is a behavior. But some desires are more conducive to scientific progress than others. Like the desire for reality not to make fools of us.

The Science Behind the Headlines, Part I: Introductory Comments

It's not all that hard or time-consuming to check the actual study behind a headline. If the article doesn't provide a link to the academic paper being cited, judge the publication (shame on them!) and then Google Scholar the paper...
