Personality and Science
The scientific study of personality involves a set of variables, and scientists have found that social attractiveness is only one aspect of personality. Therefore, the definition of personality in terms of social attractiveness is inadequate to use as a fundamental theory of personality. When psychologists study personality they look at a number of factors: social attractiveness may be one of those factors but personality is more than social attractiveness. Socially attractive people differ greatly in terms of other personality factors such as emotionality, empathy, or self-confidence. Biological, genetic, and neurological factors might influence personality too. The definition of personality must take into account issues like a person's reactions, tastes, and communication styles, not just attractiveness. Social attractiveness is also a culturally-specific variable; what makes a person social attractive in one setting might detract from his or her attractiveness in another.Social attractiveness can also be difficult to measure and requires its own parameters of definition. What one person perceives as attractive, another might find repulsive. Moreover, social attractiveness depends on others' reactions to an individual, and the
Correlational studies are also useful in the field of personality psychology. The researcher can investigate large sample sizes, correlating pre-existing data to compare two variables. Pearson's product-moment coefficient, more commonly known as the correlation coefficient, is the most common type of correlational study. More sophisticated correlational studies might use partial and multiple correlation designs. Correlations between variables can be positive or negative. A positive correlation indicates that when one variable increases, the other increases. Negative correlation indicates that as one variable increases, the other decreases. Both positive and negative correlations are useful in research. Both positive and negative correlations are meaningful when the correlational coefficient is statistically significant. Unlike experimental research designs, correlational studies cannot measure cause and effect of variables and therefore researchers need to take care when interpreting the results. Science is both a body of research and a process of discovery. As a body of research, science is a collection of tested hypotheses: educated guesses about the environment or about human behavior. As a process of discovery, science i
