If this were true, then why don't managers and Chief Officer types have their workspaces in open plans? Just think of the productivity increases that could be gained!
No, open plans are almost always for two reasons, ignoring any harm or benefit:
1) To reduce costs.
2) Politics/motivation - you have to work hard or be important to get an office.
And I'll see your one study and raise you a "Peopleware" by DeMarco and Lister; IMHO it should be required reading for everyone (especially those who decide on space layouts for knowledge workers).
