A few years back, a psychiatrist at King's College London University, monitored the IQ of workers in 80 clinical trials.
What he found is that workers distracted by phone calls, e-mails and text messages suffer a greater loss of IQ than a person smoking marijuana or losing a nights sleep. That's the down side of hyperconnectivity.
The upside exists in unified communications.
In simplifying and integrated a person's communications environment, UC can be viewed as an IQ enhancer, as compared to today's environment where employees need to juggle messages and work.
