what is psychic strong against

Psychic-type moves are super effective against Fighting and Poison-type Pokémon. However, Psychic-type moves are not very effective against other Psychic and Steel-type Pokémon. Psychic-type Pokémon are weak to Ghost, Dark, and Bug-type moves. Ghost-type moves are especially useful against Psychic-type Pokémon as they are immune to Psychic moves. In summary, Psychic-type moves are strong against Fighting and Poison-type Pokémon, but weak against Ghost, Dark, and Bug-type Pokémon.
