An interesting essay from technology critic Nicholas Carr, author of The Shallows:
In his books Empire and Communication (1950) and The Bias of Communication (1951), the Canadian historian Harold Innis argued that all communication systems incorporate biases, which shape how people communicate and hence how they think. These biases can, in the long run, exert a profound influence over the organization of society and the course of history. “Bias,” it seems to me, is exactly the right word. The media we use to communicate push us to communicate in certain ways, reflecting, among other things, the workings of the underlying technologies and the financial and political interests of the businesses or governments that promulgate the technologies. (For a simple but important example, think of the way personal correspondence has been changed by the shift from letters delivered through the mail to emails delivered via the internet to messages delivered through smartphones.) A bias is an inclination. Its effects are not inevitable, but they can be strong. To temper them requires awareness and, yes, resistance.
