Doublethink is a concept that was introduced by George Orwell in his famous novel '1984 '. It is a mental mechanism that allows people to believe sincerely and simultaneously two completely opposing ideas without a problem.
In the ten years that I have been involved with open source and open standards in the Dutch public sector, I have encountered many double thinkers. So for years I have endured “experts” and insiders patiently explaining that the migration to open source desktops within that community would be impossible, because civil servants could not work with other platforms. Asking non-techies to use anything but the Windows + Office desktop they were taught at Dutch schools would lead to disaster. It Just Could Not Happen.
The certainty with which this (to this day) is mouthed as an aphorism everywhere has always amazed me. Previously, the Netherlands had migrated from WP5.2 in DOS to Windows Word 6, yet the Earth kept turning, children went to school and there was water from the tap.
Multiple migrations, mostly outside the Netherlands, have also demonstrated that ordinary users can do their work well with alternative platforms, provided they are given some training and support (something, indeed, that is perfectly normal when migrating to new releases of the usual proprietary systems).
The same people who for years have claimed with great certainty that "It Just Could Not Happen” have been busily rolling out iPads to the many managers and directors, who for many and varied reasons discover they need one. Apparently the adoption of an entirely different platform with a totally different interface is not as problematic as was asserted for all those years. Huh?
