The polygraph is no ordinary psychometric test. Although widely used by government agencies, especially in law enforcement and intelligence, polygraph techniques have been repeatedly discredited as pseudoscience by the scientific community. Polygraphs are based on the simple notion that most people become physiologically ‘aroused’ in response to their own lies. The typical arousal response includes increased heart rate, respiration, blood pressure, and skin conductivity. There’s just one problem, however. Lots of things cause the signs of physiological arousal, including exercise, apprehension, love, and lust.

Does déjà vu hint at parallel universes? Is it evidence of reincarnation from a past life? Or is it simply a curious mental error, a telltale glitch in our brain that hints at the architecture of the mind? It depends on who you ask. Déjà vu invokes a sudden sensation of familiarity, most commonly in response to a scene, but the stimulus could also be a person, place, or even just a passing thought.

Racism is like an invasive species. As a mindset and expression of larger cultural attitudes, it tries to overwhelm its competitors wherever it sets seed. Defining victory as someone else’s oppression, racism causes imbalance and conflict in societies in which multiple races or ethnicities of people live and work. It promotes hostility within a culture, and ultimately leads to hatred and violence. Why are people racist? Why can’t we all just get along?

In February 2012, 73-year old Nepalese craftsman Chandra Bahadur Dangi was recognized for being the world’s shortest person ever recorded. The Guinness Book of World Records says he is smaller than anybody measured since 1955 when the organization first began noting such things. At a height of 21.5 inches, or just under 55 centimeters, Dangi stands as tall as most folks' knees. It’s not the first time Nepal has given us the shortest person in the world.

Intelligence is a fascinating, though complex subject, and it’s one that is difficult to study for that reason. Researchers have developed IQ tests to try and create some kind of objective, quantitative measure of human intelligence. Despite their many flaws, IQ tests present a clear quantitative bell curve with 95% of their participants scoring within a range of 70 to 130. There are a couple different classifications of IQ scores. One common classification is Wechsler’s, which ranks 90-109 as the true average.

Time zones are a universal standard used to mark the hours of the day in different locations. The reason time zones are necessary is to correct for the fact that, geologically speaking, people in different locations experience the hour at different “times” of the day. So just how many time zones are there? There are as many time zones as there are hours in a day: 24. This is no coincidence.

**People have been “keeping” time for just about five or six thousand years. They have been systematically measuring time by the hour for just about two centuries. All this amounts to less than 1% of human history. ** Before the modern era, there was no obvious reason to doubt the utility of the sun’s rough position in the sky for knowing the ‘time’ of day. And yet here we all are, minding the clock in the interest of “saving time.

How much do you think about human trafficking? If you’re living in a First World country, probably not much. What is Human Trafficking? Human trafficking is exactly what it sounds like. Just as there is trafficking in drugs, commodities, and other goods, there is trafficking in persons. Human trafficking is just another word for modern-day slavery, which is probably the most important of all human trafficking facts. It’s essential to recognize human trafficking for what it really is and to call it by its true name.

When you walk down the aisles of your local liquor store, you get bombarded with all kinds of different choices. From brands, to flavours, to types of alcohol – the choices can be confusing and endless. One of the most convoluted classifications has to do with whiskey. Whiskey can have so many permutations ranging from geographic area (Canadian, Irish, Scottish, American, etc.) to the many different types of whiskey (single malt, blended etc.
