Joint Reasoning

Joint Reasoning is a gameplay in which Sherlock Holmes, and Ryūnosuke Naruhodō, both use abductive reasoning to come to a conclusion based on logical observations made of their environment and other characters. The process involves Holmes at first making makes logical inferences to come to a conclusion. However these are most of time incorrect due to being drawn from logical yet incorrect abductions. Afterwards, it is up to Naruhodō to steer Holmes towards the actual truth, by putting his line of logic on the right track.

Trivia

 * Most of the abductive reasonings and conclusions drawn by Holmes are directly taken from Sherlock Holmes canon, but are made to be incorrect in the context of the episode's narrative. Sometimes this is even used to make fun of the original canon stories.
 * One key example of this is in The Adventure of the Unbreakable Speckled Band, where Holmes's conclusion as to what caused Kazuma Asōgi's death, which the episode directly mocks as illogical, is the actual truth behind the victim's death in the canon The Adventure of the Speckled Band.
