00:02 Hi there.

00:03 To answer this question, let's start off by talking about what science is.

00:09 Science is a body of knowledge that we add to by scientific observation and experimentation.

00:49 The thing about science is it is conducted by reputable individuals or organizations.

01:10 It is not just one person's opinion.

01:24 Okay.

01:25 So we want to contrast science.

01:28 With pseudoscience.

01:30 The prefix pseudo means fake or false.

01:34 So false science.

01:36 False science a lot of times falls into the category of urban legend, things that perhaps people have believed for years, but really have no scientific evidence to support them.

01:51 Okay, so our task here is to identify real science from pseudoscience.

01:57 All right, so the first one.

01:58 It says people can get rid of hiccups by holding their breath.

02:02 Well, that's an old, what we would call a wives tale or an urban legend.

02:07 There is no science to support that holding your breath gets rid of hiccups.

02:12 The next one says the u .s.

02:14 Surgeon general's 1964 report declared that smoking cigarettes was linked to cancer.

02:21 All right, that is science.

02:23 We have a reputable organization linking cigarette smoking.

02:32 To cancer.

02:39 And this link was established by scientists and doctors examining this relationship.

02:51 All right.
