Plumb-Ace advertises that its plumbers are more qualified than plumbers at any other major plumbing firm in the region because Plumb-Ace plumbers must complete a very difficult certification process. █████████ ████████ ███ ██ ███ ███ ██ ████ ██████████ ███ ███████ ███ █████████████ ███████ ██ ███ ████ ██████████ ███████ ██████ ████████ ███ █████ ███ ███████ ███████ ██ ███ █████████████ ████ ██████ ██ ████ ███████
The author concludes that Plumb-Ace’s certification process is not difficult to pass because most people easily pass the written portion of the process.
This is a part-to-whole fallacy because, while the written portion of the certification process may be easy, the argument gives no information about the difficulty level of the rest of the process. In other words, it assumes that what is true of the part (the written portion) is also true of the whole (the entire certification process).
