The three major issues that cut across psychology are stability versus change, rationality versus irrationality and nature-nurture issue.
Stability versus change deals with the issue of whether human beings change as they grow older or they remain essentially the same.
Rational versus irrationality illustrates the disparity between a human's mind ability to perceive and interpret correctly or incorrectly.
Nature - nurture issue centered on the relative contribution of genetic inheritance and environmental factors to human development.

People contribute to <span>antibiotic resistance by not completing their full course of antibiotics as prescribed by doctors when they are sick. This allows the bacteria to adapt to the antibiotic because the incomplete treatment did not kill the bacteria. Another way in which bacteria are becoming resistant to antibiotics is the widespread use of antibiotics in everyday consumer products, such as cleaners and beauty products. These antibiotics end up in the environment, and diluted exposure to these antibiotics by bacteria allows the bacteria to develop a resistance. </span>
