I think my definition of "most" (11 of 14) and your definition of "most" (4 of 14) differs here...which is fine. We live in the "days of Perky Pat" anyway.
Do Androids Dream of Electric Sheep?
Dr. Bloodmoney
The Simulacrum
Ubik
We Can Build You
Martian Time-Slip
The Transmigration of Timothy Archer
The Divine Invasion
A Maze of Death
Counterclock World
Radio Free Albemuth
Solar Lottery
The Zap Gun [1]
The World Jones Made
So. Yes, most.
Editors changed his shorts, too. I love the title "I Hope I Shall Arrive Soon", but PKD wanted to call it "Frozen Journey".
[1] This one was unusual in that the editor gave PKD the title and asked him to write a plot around it.
Back to original list from the parent comment that is the "above" in my comment. X denotes PKD title, O denotes otherwise:
X Time Out of Joint
X The Man in the High Castle
O Martian Time-Slip
X The Three Stigmata of Palmer Eldritch
X Clans of the Alphane Moon
X The Simulacra
X Now Wait for Last Year
O Do Androids Dream of Electric Sheep? (1968)/Blade Runner (1982)
O Ubik
O We Can Build You
X Flow My Tears, The Policeman Said
X A Scanner Darkly
O The Transmigration of Timothy Archer
O Radio Free Albemuth
So..."most" of what exactly?
But in the name of pedantry, you also have The Simulacra wrong. PKD's manuscript for The Simulacra was called "First Lady of Earth".
Eschew flamebait. Avoid generic tangents. Omit internet tropes.
Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."
