The Psychic Spectacular event is live in Pokémon Go , and brings with it a slew of Psychic-type Pokémon for trainers to catch. With events like these, the Research Tasks are updated to reflect the Pokémon in the wild. Starting Oct. 5-14, the Pokémon spawns will see an increase in Psychic types.

Pokémon Go players will even have a chance to catch a Shiny Drowzee in the wild. Rare Pokémon like Ralts will also see an increase in their spawns and may even appear in the new Research Tasks.
