Importance of Theory

Human beings have tried for centuries to explain different phenomena, events and events that occur in the world. social environment and the natural environment. How do you try to make these explanations? Here, theories play a fundamental role, because it is about new knowledge that emerges from a study or investigation carried out in a systematic way, which allows it to be given scientific validation, even when later, new studies or investigations, manage to refute these theories, presenting (for scientific validity) new results that allow said refutation.

In this sense, it forms a logical and deductive system, which can be called a theory, and is made up of a series or set of assumed premises, which are called hypothesis, and from there you can take conclusions, which serve as a rule for similar events or phenomena that can occur at any time. For this reason, theories function within science as "Models" to be able to observe, reflect and analyze the reality that surrounds us. A theory, then composed of

beginning, hypotheses or assumptions, axioms and postulates, provide a framework from which reality can be viewed and from there be studied, in any of its aspects.

One theory has two characteristics main ones, which we want to highlight here: one of them, derived from this framework from which to look at reality, The theory can be applied to similar events or phenomena that occur, and in this way, the second characteristic emerges, which is that theories can be extended, expanded, and even refuted. For example, let's take the hypodermic needle theory within the field of life sciences. communication. This theory affirms that before a certain stimulus, the individual will have a certain reaction, and then the The stimuli he receives from the mass media thus resemble a needle going through the skin. It can then be predicted what the individual's reaction to a certain stimulus will be. After a few decades, this theory was not refuted, but it was expanded: for example, the uses and gratifications theory incorporated the idea that people respond to stimuli but who choose which stimuli to receive and therefore which ones not, based on the choice of certain products or offers of the mass media, which may be gratifying to you or which in some way satisfies a need by consuming them.

This case is by way of example, within a specific scientific field, it can be replicated in different cases in all existing sciences and scientific disciplines.
