Document Summary
Lots of other people jumping on the psychology research bandwagon . Lots of misunderstanding of how science actually works. Nobody says proof in science we say evidence. Ex: at halftime of football score is 43-3. Most people will bet team up by 43 will win. Competing theories work in the same way. If score 24-21 at halftime no one will probably bet on either team. Theory - explanation using an integrated set of principles that organizes and. Theories aren"t right or wrong or proven or disproven. Theories put many pieces together and a theory is a nice way of organizing all of. Example: what"s the operational definition of reading speed . What specifically do you mean by reading speed . There is no single way to define personality because there are many different aspects of it. But extraversion has pretty good construct validity.
