The "Vulcan mind meld", introduced in this episode, was originally a way of working around a warning from NBC's "Standards and Practices" department. In an earlier draft of the script, the plan had been to have Spock hypnotize Van Gelder, but writers were told that they must have hypnotism performed "by DOCTOR McCoy rather than MISTER Spock" unless they could establish that Spock had been specially trained to do this.
