Introverted Intuition (Ni): Ritchie always contemplates his next move instead of jumping straight into anything. When he decided to search for the legendary Pokemon Lugia, he did extensive research on the Whirl Islands (where Lugia was rumored to be found) before even traveling to the area to look. On arrival, he concentrated his search on the most likely areas to find Lugia. He anticipates that his Pokeballs might get mixed up with those of other trainers, so he marks his own with stars as a precaution. When Team Rocket tricks all Pokemon League participants into giving them their Pokeballs, Ritchie discovers their ploy with a very small sliver of information.
Extroverted Feeling (Fe): Ritchie is polite and courteous to everyone he meets, going out of his way not to cause offense. He wears his heart on his sleeve for all to see; when scheduled to have a battle with Ash, Misty accuses him of luring Ash away from the arena to force a disqualification of the latter. Ritchie puts forward no logical argument for why that is untrue, but he manages to convince Misty anyway. He even pleads with the referee not to disqualify Ash in his continued absence, because the two of them promised each other a great battle.
Introverted Thinking (Ti): Ritchie is very curious; his natural investigative tendencies led him to the Whirl Islands to search for Lugia after hearing rumors of the legendary Pokemon’s presence. For the first five rounds of the Indigo League, he uses only three Pokemon (also showing Ni), and two of these are not conventionally considered powerful. He did not even fight power with power when Ash decided to battle him with his mighty Charizard, opting instead to use a Pikachu, which would have lost the battle had Charizard given the battle 100 percent. Ritchie is also mechanically inclined enough to fix an elevator when it breaks down (Ti-Se, usually seen in an ISTP).
Extroverted Sensing (Se): Ritchie prefers to act deliberately rather than spontaneously, but he can think quickly to get himself out of a tough spot. When falling from a height, he instinctively calls on his Butterfree to help him land softly. As noted above, he has the sensory awareness to fix a broken machine. Nor are aesthetics completely lost on him; he always comes up with cute nicknames for his Pokemon instead of referring to each one by its species name.
