I need help recognizing bias in research reports.....?

1. In his research, Gordon Allport identified about 18,000 human traits. Allport concluded from his research that traits are the building blocks of personality. Allport's conclusion is about as sound as a skyscraper constructed without a foundation.

2. The research report explores the five approaches to the study of personality-trait theory, psychoanalytic theory, learning theory, humanistic theory, and sociocultural theory. I have collected a vast amount of data on the subject during my past 20 years as a humanistic psychologist. My research report uses this information to answer the question. How does personality develop?

3. One participant in the case study was a high school student named Vilay. Since Vilay was raised by parents who had grown up in Japan, she tended to be rigid and controlled in her emotions. This was obvious because she looked uncomfortable expressing her feelings to the interviewer.
