In a small town, every complaint filed about a plumber's work was filed against Moore, who has a relatively small business. ██ █████ ██ ████ ████████ ████ █████ ██ █ ████ ███████ ███ ██████ ██ ███████ ██ ██ ██ █ ████ ████
The author concludes that Moore is not a good plumber and cannot be relied upon to do good work because every complaint about a plumber in this small town was aimed at Moore’s business.
The author neglects to rule out any alternative explanations for these complaints. What if there were very few complaints from anyone in the town about any plumbing services, and they just happened to be towards Moore? What if these few complaints comprised just a small percentage of Moore’s services, and a vast majority of the time, his customers were satisfied with his work? What if Moore is the only plumber in this small town, so any possible complaint must be directed at his business? Without ruling out any of these alternatives, the author’s argument is very weak.
