===Meaning===
'''Scientific evidence''' is any [[observation]]s or [[result]]s that are [[repeatable]], [[reproducible]] and [[valid]].

===About Scientific Evidence===
: '''Scientific evidence''' is intended to be [[objective]] which means anyone can [[observe]] the same [[evidence]] regardless of their beliefs.
: '''Scientific evidence''' is gathered following a set of practices designed to reduce the [[bias]] of the person performing the [[investigation]].
: '''Scientific evidence''' is not the same as the [[evidence]] used in a court of law.
: Some forms of '[[evidence]]' are not accepted by [[scientist]]s, including:
:*[[Anecdotal Evidence]] - '[[Evidence]]' based on a personal experience. [[Scientist]]s don't trust this because people can make mistakes, misunderstand something they've seen or even hallucinate or dream things which have not happened.
:*Intuition - Ideas that seem true because they make sense are not counted as '''scientific evidence'''. Just because something seems reasonable, interesting or makes sense does not mean it is true.
:*Tradition - Ideas that have been passed on through generations. Just because many people say something is true, doesn't mean it is true. Such ideas were usually made thousands of years ago at a time when the wheelbarrow was a state of the art invention and most people believed disease was caused by demons.
