Do birds of a feather flock together or do opposites attract? Does haste make waste or should you strike while the iron is hot? Adages like these-or conventional wisdoms-shape our social life. This Fourth Edition of Second Thoughts reviews several popular beliefs and notes how such adages cannot be taken at face value. This unique text encourages students to step back and sharpen their analytic focus with 24 essays that use social research to expose the gray areas of commonly held beliefs, revealing the complexity of social reality and sharpening students' sociological vision.
