A research team trains two research assistants to code behavioral observations from video-recorded parent-child interactions. They independently code 50 videos as showing either "warm parenting" or "authoritarian parenting," and their classifications agree on 44 of the 50 videos (88% agreement). However, when the researcher calculates Cohen's kappa, the value is 0.71. Which statement best explains why Cohen's kappa (0.71) is substantially lower than the raw agreement percentage (88%)?
