Many parents rigorously organize their children's activities during playtime, thinking that doing so will enhance their children's cognitive development.
Conclusion
Rigorously structuring playtime for your kid will not enhance the kid’s cognitive development.
Evidence
Expecting rigorous playtime to produce a creative and resourceful kid is like thinking that imposing a rigorous plot/character structure on a writer will result in the writer making a good novel.
Evaluation
This argument relies on a comparison/analogy, so we object to these sorts of arguments by pointing out meaningful differences.
Is there some reason why imposing a plot/characters on a writer wouldn’t have good results, but imposing a rigorous schedule on a child could help his/her cognitive development?
Novelists are usually full-grown adults, whereas kids have developing brains, so maybe we could say that rigorous structure is good for a developing brain, even if it isn’t great for creative adult tasks like novel writing.
The author has also not spelled out the missing part of his analogy: he’s assuming that if you told someone what plot/characters they had to use, they would not be likely to produce a good novel. The author is also drifting from the idea of “enhancing cognitive development” to the idea of “creative and resourceful child”.
Goal
Look for an answer spelling out the author’s missing assumption, the author’s language drift, or, more likely, pointing out a salient difference between the effect of structure on a child’s brain vs. the effect of imposing structure on a novelist.
