What Women Want (2000)

Continuity mistake: When Nick first enters Sloane Curtis and is talking to one of his male co-workers, in the background there is a man in the typing away at his computer. He gets up and walks off, then the camera angle changes for a few seconds. When it returns, the man returns to his computer. It cuts away and returns a few more times, rather quickly, each time showing the man returning to his computer. (00:08:35)

J.M. Perkins: If you know what women want, you can rule.

Trivia: The fictional childhood of Nick, growing up in a burlesque club surrounded by beautiful, nearly naked women who adored him, is bizarrely similar to the actual childhood of Alan Alda, who plays the boss character. Alan Alda's father ran a burlesque club, and apparently the strippers and dancers treated the young Alda as a mascot, even keeping him in the changing room as they got dressed. However, as an adult Alda became an activist for feminist causes, rather than the chauvinist effect it had on the fictional Nick.

Question: Why is it that Nick can't hear what his two women co-workers are thinking?
