Biofields

Ever heard, or said, something like, "I went into that room, and you could cut the tension with a knife" or, “I went into that room, and I felt at peace."

Deepak Chopra suggests this is because humans emit an electromagnetic field based on our current mood.

One study found some level of efficacy from bio-field therapies (reducing pain, anxiety, dementia-related behaviors, fatigue). Chinese medicine has long used similar techniques such as qigong. The therapy, however, remains controversial.

Geography & Voice

Each individual language has a few number of sound units (phonemes) and research suggests geography may affect which phoneme's usage become commonplace.

The ejective consonant (e.g. "P" or "K") phoneme exists in ~20% of the languages. Of 500+ languages  studied, research shows that languages spoken at higher elevations were more likely to use ejective consonants. This may be because lower air pressure eases the burst of air characteristic of this phoneme.

Price Confusion

Research finds that customers have, ironically, a harder time choosing between similar products (e.g. cereal) if the products are priced the same.When prices were different, products were seen as similar, making it easier to select one product. But identical prices made the products seem less similar.

Wolf Howls for Friends

Research shows that when separated from a pack wolf, the closeness of friendship - not the wolf's rank - dictates the howl's intensity.

IQ Not Directly Related to Economic Development

Research finds that "differences in the timing of agriculture transition and the histories of States, not population IQ differences, predict international development differences before the colonial era. " Average IQ of populations seems to be related to various stages of nations' modernization, not due to economic development.

Humans are Moody

Research finds evidence of distinct emotional periods in the 20th century, a general decrease in the use of emotion-related words, and that American English is more “emotional” than British English in the last 50 years.

Pronouns and Individualism

Researchers hypothesized that pronoun usage reflects increasing individualism in American culture. Their research found that for American books from 1960-2008, use of, "first person plural pronouns (e.g., we, us) decreased 10% first person singular pronouns (I, me) increased 42%, and second person pronouns (you, your) quadrupled."
