Because they're positioned with higher status in a hierarchy?
If a student makes a mistake, the professor merely points out the mistake.
If a professor makes a mistake, a student will at least be uncertain whether a mistake was made, and will have to go to much greater length to point out the mistake.
A few templates, a couple of text expanders, and a brief mentoring in soft skills, active listening, and written comms would resolve any major issues.
Granted, Gaussian distribution guarantees that the above wouldn't cover all cases.
But when working with people in the normal job, nobody is watching them type they just eat the sausage.
I can relate. I don’t have anxiety generally with work and have been praised on my interactions with customers. But I feel anxious during interviews because they are actively trying to judge me.
If someone is doing an internal facing role, especially engineering, it may only come up during things like team stand ups, or certain types of design reviews, or not at all. So less of a problem.
Then again, maybe I'm biased because I write the same sentence multiple times in quick succession. And I go back and re-write previous sentences if they don't flow well with what's coming next. But when people have watched me do it, they have only expressed wonder and admiration over it, never negative feelings.
What doesn't work is when someone starts verbally editing my first draft the instant I've typed it out. Yes, I know it's bad -- it's the first draft. I just needed to get something on the page to see where I should go next.
I would imagine that, if anything, seeing you pause after an initial draft, adjust some grammar and tone, pause...even re-write a sentence or paragraph - and then say "done"...would impress, not detract.
As far as your technique, drafting then editing down is a totally legit way to write. I wish more people did that!
Adaptation only goes so far. More training won't turn a dwarf into a basketball centre, or a heavyweight bodybuilder into a champion marathoner. Sometimes you've got to work with what you have, both in terms of abilities and limitations.
Intellectual and psychological limitations may be less manifestly visible but are no less real.
Just like if you're nervous about driving on the freeway, or flying in an airplane.
Heck, I remember buying my first phone answering machine. I froze up repeatedly trying to record the message. After a while, that problem went away.
I've been driving more than 20 years and almost none of the anxiety I experience because of it ever went away. If I know the roads already it's a little better, but every single day I have to power through the anxiety to get to where I need to be going. It doesn't get better.
Hotels give me anxiety even though I actually lived in a hotel for six months.
My husband developed anxiety later in life doing things he has done for years.
What you're talking about is just normal human emotions, when people refer to "performance anxiety" they are usually referring to an anxiety disorder. Crippling anxiety that doesn't spontaneously resolve.
If you're in your 50s and it's still a constant problem, quite possibly not.
Again, people aren't infinitely malleable, and don't all fit in standard packages.
Even seasoned stage performers often face crippling anxiety before performances late in their careers. Others take their own lives, often at a young age. Dick Cavett is among those who've suffered crippling depression and taken extended leaves due to it.
