Logical Thinking

  Links to Logic PSAs

Beginning in the 1970's, Saturday morning television featured educational spots of 30 or 60 seconds as an attempt by the big three U.S. networks (ABC, CBS, NBC) to instruct the kiddies as they watched their morning cartoons. These interstitial programs usually took the form of musical education short films such as ABC's popular and now cult favorite Schoolhouse Rock (1973-1980) and CBS' Bicentennial Minute (1974-1976). These programs taught such things as Multiplication tables, Grammar, American government and Science.

Had NBC decided to teach principles of sound reasoning in the mid-1970's they could do no better than to have the logical Mister Spock do the teaching. As an addition to the the two-dozen or so Public Service Announcements I created featuring the animated crew of the Starship Enterprise, I have created a new series of PSAs featuring Mr. Spock called "Logical Thinking."

I intend to make a dozen or so of these in each of which Spock corrects some crewmembers after overhearing them employing a logical fallacy in their discussions. Using the Vulcan science officer to educate them in proper reasoning is "Only Logical" as he states at the end of each PSA.

These new PSAs were written seriously just like the ones that were seen on Saturday mornings in the 1970's and 1980's, but when viewed with today's sensibilities, they will probably seem quaint and perhaps humorous. They have been uploaded to youTube and they can be watched below. Enjoy...
