Neither of us have statistics on that, so a yes/no battle here is pointless. I and many others find it to be a useful signal when someone demonstrates intense anxiety under pressure, you and many others do not. Agree to disagree.
If your programmers are having to work under pressure then you're doing it wrong. It is the job of the manager to create an environment where people are as effective as they can be, and creating artificial space for developers is part of that. (Read Peopleware for more on this.)
If you're only willing to consider people who can somewhat function under artificial pressure, then you're passing up a lot of top-notch candidates for very bad reason.
