Lack <strong>of</strong> consensus on exactly what theory is may explain why it is so difficult to<br />

develop strong theory in the behavioural sciences (Sutton <strong>and</strong> Staw, 1995), so I will<br />

start from a primer on laws, hypotheses, <strong>and</strong> theories.<br />

LAWS, HYPOTHESES, AND THEORIES<br />

In both academic <strong>and</strong> practitioner usage, law, hypothesis, <strong>and</strong> theory are too frequently<br />

used interchangeably. By the principles <strong>of</strong> the Scientific Method, a theory refers to<br />

something has been sufficiently proven through past research, <strong>and</strong> is generally accepted<br />

as being true. A law is a statement <strong>of</strong> fact accepted to be true in every case by a large<br />

majority <strong>of</strong> those familiar with the phenomenon the law describes. Laws are similar to<br />

mathematical postulates (postulates are axioms, generally accepted principles<br />

sanctioned by experience). Therefore, laws do not need further pro<strong>of</strong>. They are based<br />

upon the fact that they have always been observed to be true. Most laws are simple<br />

rather than complex. There are widely known laws in physics, the law <strong>of</strong> gravitational<br />

attraction, Newton’s laws <strong>of</strong> motion, the laws <strong>of</strong> thermodynamics, Boyle’s law <strong>of</strong> gases,<br />

<strong>and</strong> the law <strong>of</strong> conservation <strong>of</strong> mass <strong>and</strong> energy.<br />

An hypothesis is a proposition derived from observation <strong>and</strong> received knowledge. It is a<br />

statement proposing an explanation <strong>of</strong> a single event or phenomenon based upon what<br />

had been observed in the past, but which has not been sufficiently researched to be<br />

accepted as proved. Studies are designed <strong>and</strong> employed to support or refute an<br />

hypothesis by experimentation or continued observation. Principles <strong>of</strong> the Scientific<br />

Method state that an hypothesis can be disproven, but not proven true; the source <strong>of</strong> the<br />

ubiquitous null hypothesis, Ho, there is no significant difference ... etc.<br />

A theory is an explanation <strong>of</strong> a set <strong>of</strong> related observations or events based upon<br />

hypotheses that have not been completely <strong>and</strong> sufficiently verified multiple times by<br />

unaffiliated groups <strong>of</strong> researchers. Frequently a theory is ultimately accepted to be true<br />

by a scientific community after a consistent string <strong>of</strong> studies with no falsifying results,<br />
