In gen 1 the only ghost type was part poison and there were no good bug moves making psychic extremely overpowered and dark a necessary opposing force. In the generation i games psychic type pokémon were at the center of a balance issue. The dark type was introduced in the second generation of pokémon games as a measure to balance the types.
This chart shows the strength of the psychic type against every type combination. Dark was only introduced to weaken psychic types. Multiple sources mention that ghost type moves are super effective on psychic type pokémon.
Several game guides stated that ghost was super effective on psychic and an in game trainer at saffron city says that psychic pokémon fear only ghosts and bugs. There were no dark or steel types. In generation i there was no way to do super effective dragon type damage since the then only dragon type attack dragon rage always deals 40 hp of damage.
As a result the issue was rectified in generation ii with the addition of steel and dark types an added weakness to ghost type moves as opposed to previously being immune to them as well as some moves that are strong against psychic types. As such this was the only case when two different types were ever super effective against each other. Psychic pokémon stat averages 73 6.
The bug type was the most common 4 weakness in generation i with 11 pokémon doubly weak to it mainly due to poison type having a weakness to it at the time. Level 2 47 points 7 years ago.
