Principle JustifyDiff: Easy
Logic Breakdown
Passage Summary: My last book was a hit because I worked with a partner, so I'm going to do that again to make sure my next one is a hit too.
Conclusion: The writer should partner with another author on their upcoming book to ensure its success.
Reasoning: The writer's previous book was a collaboration and sold very well, so repeating that strategy should yield the same result.
Analysis: This argument relies on the assumption that a past success was caused by a specific factor and that this factor will reliably produce the same result in the future. To justify this, we need a principle that bridges the gap between 'it worked once' and 'it will work again.' Look for a principle stating that if a particular method led to a desired outcome previously, one is justified in using that same method to achieve that outcome again. Apparently, this writer believes lightning can be coaxed into striking twice if you just bring a friend along.
