You cherry pick facts you like and ignore the ones you don't. It's called confirmation bias. An experiment is still a choice.
Also Stewart was known for his insistence that the character and set be run a certain way. While the rest of the cast had fun, he didn't - which led to a lot of on set conflict. Though he later "let his hair down" so to speak and began to enjoy the fun his crew had. This was later inferred in the last episode when his crew invited him to the poker table in the last episode - an indication he was always part of their group (behind the scenes) if he'd relax. But that stoic portrayal was his idea and his execution - his choice.
Season 3 TNG season finale, it was not known if Picard would return because he was likely going to be replaced. His stoic attitude was primarily why and fans did not relate to him at the time. They used the finale and season 4 premiere to give him a more relatable and emotional dynamic (Patrick Stewart related this story years later).
It sounds to me like you pick which story in your head fits what facts you accept and doesn't fit the facts you reject. You're still wrong. And, unfortunately, that's bad for your entire premise and responses.
