Pokémon Red and Blue / GAME HISTORY
Why Does Lick Fail Against Psychic Pokémon in Red and Blue?
The original type table blocks Lick, while Night Shade follows a different damage route.
Short answer
The original Red and Blue type table gives Ghost attacks no effect against Psychic targets. Lick therefore fails against a Psychic Pokémon. Night Shade is a fixed-damage exception, so this is not a rule that every Ghost move fails.
Scope: Original Game Boy Pokémon Red and Blue; type table checked in the community disassembly.

The move matters, not just the Pokémon using it
Choose Lick against a Psychic target and the Ghost-to-Psychic entry blocks its normal damage. Repeating Lick does not get around that entry. The obstacle is the matchup, not a run of ordinary misses.
A Pokémon’s species type and the type of its selected move are different things. Sending out a Ghost Pokémon does not make every move in its menu a Ghost attack, and it does not make Lick a useful answer to this particular target.
Why Night Shade can still deal damage
Night Shade uses fixed damage through a different route. It is therefore a mistake to extend Lick’s result to every Ghost-type move. The useful comparison is the action selected in the battle menu: Lick meets the zero multiplier, while Night Shade is not resolved through that same ordinary damage calculation.
The old table is the evidence
The pret/pokered project preserves the Ghost-to-Psychic no-effect entry. Bulbapedia’s generation-specific matchup history provides the wider context. A type chart from a later game is not a replacement for that original table. These are the rules of the Game Boy release, not a new warning about Psychic matchups throughout the series.
