Yet another weird SF fan


I'm a mathematician, a libertarian, and a science-fiction fan. Common sense? What's that?

It Takes a Big Man to Admit He's Wrong

I used to think organic foods were identical to conventional foods. I was wrong:

Analysis of the wheat found the conventionally-grown seeds to have an average 10 per cent higher protein content than the organic seeds. Other differences between the samples (e.g. in mycotoxin levels, grain size, energy content or pesticide residues) could not explain the preferences shown by the birds.

………

Dr McKenzie explained: "Conventionally-grown crops tend to contain significantly higher levels of protein than those grown organically due to the application of inorganic nitrogen fertilisers in conventional farming systems.

"This makes our findings potentially applicable across many food types and suggests the issues surrounding organic food are not as cut and dried as some might think."

I used to think immigration would have no effect on crime rates. I was wrong:

Wadsworth’s research suggests that, controlling for a variety of other factors, growth in the new immigrant population was responsible, on average, for 9.3 percent of the decline in homicide rates, and that growth in total immigration was, on average, responsible for 22.2 percent of the decrease in robbery rates.

Exactly why growth in immigration is accompanying decreases in violent crime is hard to determine with city-level data. Some have suggested that immigrant communities are often characterized by extended family networks, lower levels of divorce, and cultural and religious beliefs that facilitate community integration.

Wadsworth notes that “criminologists have long known that these factors provide buffers against crime.”

It takes a big man to admit he's wrong and I'm a big man (at least from side to side).
