The Handbook of Research Methods in Experimental Psychology presents a comprehensive and contemporary treatment of. This article examines experimental psychology, the controlled study of behavior with an A good source for that type of effort is the book by Antonio.
Let us explore what this means in more detail. What characteristics of the scientific approach make it a desirable way to learn about and arrive at beliefs about the nature of things? Perhaps the best way to answer this question is to contrast science with other modes of fixing belief, since science is only one way in which beliefs are formed.
More than one hundred years ago, the American philosopher Charles Sanders Peirce compared the scientific way of knowing with three other methods of developing beliefs. He called these the authority, tenacity, and a priori methods.
A trusted authority tells you what is true and what is false. Young children believe what their parents tell them simply because Mommy and Daddy are always right. As children get older, they may discover, unhappily, that Mom and Dad are not always correct when it comes to astrophysics, macroeconomics, computer technology, and other specialized fields of knowledge.
Instead, some other authority may be sought. Religious beliefs are formed by the method of authority.
Long after Catholic children have rejected their parents as the source of all knowledge, particularly about religious doctrine, they may still believe that the pope is infallible. Believing the news you see on television means that you accept CNN or some other news network as an authority.
You may believe your professors because they are authorities. Since people lack the resources to investigate everything they learn, much knowledge and many beliefs are fixed by the method of authority. It is most pleasant in a troubled world to have complete faith in beliefs handed down to you.
Another method of fixing belief is one in which a person steadfastly refuses to alter acquired knowledge, regardless of evidence to the contrary. The method of tenacity, as it was termed by Peirce, is commonly seen in racial bigots who rigidly cling to a stereotype even in the presence of a good counterexample.
Although this method of maintaining a belief may not be entirely rational, we cannot say it is completely without value.
The method of tenacity allows people to maintain a uniform and constant outlook on things, so it may relieve them from a certain amount of stress and psychological discomfort.

The third nonscientific method discussed by Peirce fixes belief a priori. In this context, the term a priori refers to something that is believed without prior study or examination. Propositions that seem reasonable are believed.
This is an extension of the method of authority. However, there is no one particular authority being followed blindly in this method. The general cultural outlook is what seems to fix belief a priori.
People once believed the world was flat, and it did seem reasonable to suppose that the sun revolved around the earth as does the moon. Indeed, the world does look flat if you are not in a spacecraft.

The tenacity and a priori methods are similar in that they minimize the possibility of being influenced by conflicting opinion. In the method of tenacity, other points of view, although noticed, are completely discounted. Thus, a racial stereotype is preserved despite other evidence, such as the good qualities of a person of a different race who lives next door.
In the a priori method, other points of view go unnoticed. For example, the sight of a ship disappearing from bottom to top, instead of all at once, as it leaves port may seem irrelevant if you already know the world is flat. Science is based on the assumption that events have causes and that we can discover those causes through controlled observation.
This belief, that observable causes determine events, is known as determinism. If we define scientific psychology as well as science in general as a repeatable, self-correcting undertaking that seeks to understand phenomena on the basis of empirical observation, then we can see several advantages to the scientific method over the methods just outlined.
Let us see what we mean by empirical and self-correcting and examine the advantages associated with those aspects of science.
The first advantage of the scientific method is its emphasis on empirical observation. None of those other methods relies on data observations of the world obtained by systematic observation.
In other words, there is no empirical basis for fixing belief. By definition, the method of tenacity refuses to consider data, as does the a priori method. Facts that are considered in these other modes of fixing belief are not ordinarily obtained by systematic procedures. The second advantage of science is that it offers procedures for establishing the superiority of one belief over another.
Science overcomes this problem. In principle, anyone can make an empirical observation, which means that scientific data can be public and can be repeatedly obtained. Through public observations, new beliefs are compared with old beliefs, and old beliefs are discarded if they do not fit the empirical facts.
This does not imply that each and every scientist instantaneously drops outmoded beliefs in favor of new opinions. Changing scientific beliefs is usually a slow process, but eventually incorrect ideas are weeded out. Empirical, public observations are the cornerstone of the scientific method, because they make science a self-correcting endeavor. A theory can be crudely defined as a set of related statements that explains a variety of occurrences.
The more the occurrences and the fewer the statements, the better the theory. The law of gravity explains falling apples, the behavior of roller coasters, and the position of bodies within the solar system. With a small number of statements about the mutual attraction of bodies, it explains a large number of events. It is therefore a powerful theory. This does not necessarily mean it is a correct theory, since there are some events it cannot explain.
Theory in psychology performs two major functions. First, it provides a framework for the systematic and orderly display of data—that is, it serves as a convenient way for the scientist to organize data. Even the most dedicated inductive scientist will eventually have difficulty remembering the outcomes of dozens of experiments.
Theory can be used as a kind of filing system to help experimenters organize results. Second, it allows the scientist to generate predictions for situations in which no data have been obtained.
The greater the degree of precision of these predictions, the better the theory. With the best of intentions, scientists who claim to be testing the same theory often derive from the theory different predictions about the same situation.
This unfortunate circumstance is relatively more common in psychology, where many theories are stated in a loose verbal fashion, than in physics, where theories are more formal and better quantified through the use of mathematics. Although psychologists are rapidly becoming equipped to state their theories more precisely through such formal mechanisms as mathematics and computer simulations, the typical psychological theory is still not as precise as theories in more established, older sciences.
The theory of diffusion of responsibility organizes a substantial amount of data about social loafing. More important, the theory seems to account for a remarkable variety of other observations.
Likewise, proportionately more people committed themselves to Christ at smaller Billy Graham crusades than at larger ones. Theories are devised to organize concepts and facts into a coherent pattern and to predict additional observations. Sometimes the two functions of theory—organization and prediction—are called description and explanation, respectively. Wielding a Gun.
