What Americans Own

Wealth is your overall financial picture, including all your assets. Assets can be considered anything of value that can be converted into cash, including things like cash itself, real estate holdings, investments, and personal property. According to the Federal Reserve, as of September 30, 2022, the combined assets of US households and nonprofit organizations were worth about $162.5 trillion - $54.8 trillion in non-financial assets (e.g., housing, land, machinery, vehicles) and $107.7 trillion in financial assets. Here’s the Fed’s breakdown of financial assets…

Genetically Modified Crops: Benefits, Concerns and Risks (in One Table)

The biggest threat to biodiversity is loss of habitat. Agriculture is the main driver of habitat loss on the planet and a major source of greenhouse gas emissions. Climate change will reduce agricultural productivity unless crops become more resilient. GM crops require less land and are more resilient than conventional and organic crops.

Stigma, Self-Control, and Drug Abuse

In other words, if carrots and sticks change the behavior, then the person has at least some control over the behavior, which is another way of saying: if one is able to engage in goal-directed behavior (e.g. approach carrot, avoid stick), one is responsible to some degree for one’s actions and the outcomes of those actions…That’s where “stigma” comes in. According to the World Health Organization (WHO), “stigma in the context of health is the negative association between a person or group of people who share certain characteristics and a specific disease, including mental illness”. And per the voluminous literature on stigma, a common stigmatizing stereotype associated with mental health disorders such as drug addiction is that people are responsible for their condition.

Incentives, Triggers, and Drug Abuse: Is the Science Settled?

Moral hazard is a situation where individuals have an incentive to increase their exposure to risk because they do not bear the full costs of that risk. I’m guessing a possible moral hazard associated with needle exchange programs is that these programs would lead to greater drug abuse by reducing the perceived risks of needles. And with opioids, more drug abuse would mean a higher likelihood of death by overdose.

Does a Good Cause Justify Distorting the Scientific Record?

President Clinton eventually signed the the Kyoto Protocol to the UN Framework Convention on Climate Change, but he never submitted it to the Senate for ratification. That’s because the Senate had already made it crystal clear that the vote would not go well: just two years before the Senate has passed a resolution 95-0 telling Mr. Clinton not to sign any treaty that committed the US to cut emissions without also requiring undeveloped countries to do so.

The Politics of Missing Data

To quote the New York Times: “Since then, similar comprehensive research has been blocked, in part by tenants’ advocates who believe the findings would be “politicized” and become a referendum on rent control…”

The Power of Hassle to Change Human Behavior

According to John Kelly of Mashed Radish , the word “hassle” may have originated from a blend of words that represent small, intense repeated actions, such as haggle and tussle or harass and hustle. To call something a hassle is to say it requires an annoying amount of time and energy while engaged in a series of small, intense actions. For example…

The Scientific Process

“Accepted theories are the best explanations available so far for how the world works. They have been thoroughly tested, are supported by multiple lines of evidence, and have proved useful in generating explanations and opening up new areas for research. However, science is always a work in progress, and even theories change.” - How Science Works.

Reactions to Inequality, Part II: The Role of Perceived Control

Perceived control also influences how people feel when exposed to others who are "higher" than them on some metric.  Studies on social comparison have found that "upward comparison" (comparing oneself to "higher" others) was "debilitating only when accompanied by low perceived control".

Reactions to Inequality, Part I: The Role of Hope

“When inequality loses its association with hope and instead becomes interpreted as a signal of a rigged society, higher inequality relates to lower well-being.” - Buttrick, N. R., S. J. Heintzelman, et al. (2017). Inequality and well-being.

What is Misinformation, Part II: Disseminating Physicians

The California legislature recently passed Assembly Bill (AB) 2098, which would “designate the dissemination of misinformation or disinformation related to the SARS-CoV-2 coronavirus, or ‘COVID-19’ as unprofessional conduct”. AB2098 has been signed by the governor and is scheduled to take effect on January 1, 2023. Here are some excerpts from the new law…

The Top Ten Energy-Consuming and CO2 Emitting Countries in the World

Countries that consume a lot of energy tend to have large populations, advanced economies, or both. However, high country-level energy consumption may be coupled with low per capita consumption, because some countries are populous but still developing and largely rural, as is the case with India and Brazil.

The CO2 Series, Part II: Global Trends in Atmospheric CO2

Carbon dioxide (CO2) is Earth’s most important greenhouse gas, responsible for about two-thirds of the total heating influence of all human-produced greenhouse gases (Lindsey/NOAA Climate.gov, 2022). The last time atmospheric CO2 amounts were this high was more than 3 million years ago during the Mid-Pliocene Warm Period when global surface temperature was 2.5–4°C (4.5–7.2°F) warmer than during the pre-industrial era and sea levels were at least 16 feet higher than they are today.

So are we making much progress in reining in atmospheric CO2?…

One Person's "False Equivalence" is Another's "Apt Comparison". How Do We Know the Difference?

Then again, false equivalence is much more than a matter of flawed reasoning or cognitive bias. Comparisons reflect an understanding of how the world works, what leads to what and over what time frame. A problematic comparison may stem from empirical error, logical error, or both. But people rarely hold themselves to some scientific standard of accuracy. Sometimes a comparison is made to serve a larger point and it’s not really advancing the conversation by nitpicking minor errors.
