As Skeptics.SE grows, there are some topics that clearly cause concern and have been richly mined with questions and answers.

While tags link many of these questions together, it can be difficult to get an overall view of what has been discussed in a topic by a flat list.

The question (with a slightly tongue-in-cheek title) provides a place for people to help out by providing an overview (in whatever format is most convenient) to allow people to discover what has already been covered.

Intelligence

The topic of human intelligence makes a regular appearance on Skeptics.SE - particularly what may cause or correlate with high or low intelligence.

Here is a summary:

Notes:

  • Some questions make the distinction between Intelligence and IQ.
  • Ethnicity, Body Features, Personality and Psychology are all strongly correlated with genetics, while Life Choices are correlated with Ethnicity, making some of the category distinctions here arbitrary.
  • Some questions ask about correlation, while others ask about causation. Some are about permanent and others are about temporary effects. Most claims assert a direction of the expected effect.

Sweeteners

There are a large number of questions about the health effects of sugar and artificial sweeteners - too many to list as related questions.

This chart provides a map. Hopefully, it will help people discover duplicate questions more easily.

Notes:

  • Both open and closed questions are included.
  • Included if the claim is mentioned in the question, or addressed in the accepted answer or a highly-voted answer.
  • Some wide-ranging questions appear in multiple places.
  • HFCS (High-Fructose Corn Syrup) is nominally listed as a natural sweetener, as it it generally isn't intended for inclusion when talking about artificial sweeteners.
  • Cane and Brown Sugar are both included with sugar

Racism

Many questions have been asked that explore whether race-based claims (including affirmative action and distinctly racist claims) have a scientific backing. Included here are questions based on ethnicity, country, skin-colour and other factors that are strongly correlated with race.

Historically, these questions have rarely earned good answers, and are often closed, because, on examination, they are poorly constructed.

I've ignored some borderline questions (e.g. 1, 2, 3) as not race-based.
