"Savvy politicos know that not just any poll will do. Online polls, in which anybody can vote, are not legitimate. The reason is because they do not accurately reflect the voting public. Imagine, for instance, a poll on Starbucks' website asking readers if they like to drink coffee every day. In this hypothetical poll, it would not be a surprise if nearly 100% of respondents said "yes," even though only 64% of Americans drink coffee every day. The reason is obvious: People who are using Starbucks' website are probably coffee drinkers."

SCIENCE (from the Latin for 'knowledge') informs wisdom, reason and humanism. This is a 4-legged worldview within reality that maximizes well-being for individuals and society.
