A new study shows a link between bad technology and higher stress levels of employees. Researchers from American computer company Dell Technologies led the study. Dell partnered with neuroscience company EMOTIV on the study. The research involved experiments in which brainwaves were measured as people were put through a series of bad technology experiences. The experiments involved adults of many ages with different levels of computer skills. Subjects were tested with simple computer problems, like troubled sign-in operations. Others dealt with slow-speed connections to the internet. Still others experienced system crashes. “The moment people started using bad technology, we saw a doubling of their levels of stress,” said Olivier Oullier, president of EMOTIV. “I was a bit surprised by that, because you rarely see those levels going so high,” he told Reuters news agency. The experiments showed that technology-related stress had a lasting effect, Oullier added.
