Like to think of yourself as a spontaneous sort? You are so predictable.
We are such creatures of habit that scientists can accurately predict where we’ll go and when we’ll go there more than 90 per cent of the time.
Most of us can usually be found within one to three miles of our home.
Even those with a long commute generally do the same things at around the same time each day, the journal Science reports.
In other words, most of us are stuck in a rut.
Researcher Albert-Laszlo Barbasi said: ‘If you drive for one and a half hours to work and back, three hours of your day are taken away so you have little freedom to be spontaneous.
‘You are working, and travelling home and pretty much crashing and preparing for the next day.’
Globetrotters also follow a well-trodden path, tending to follow familiar routes, rather than visiting new places.
Professor Barbasi, of the respected Harvard Medical School in the U.S., analysed three months of mobile phone data from 50,000 people.
Logged by billing companies when they made or received calls and text, it allowed the researchers to pinpoint their location to within two miles.
The researchers used this information to build up a pattern of each person’s movements during the week and at weekends.
They found they could predict where a person would be at given time and get it right up to 93 per cent of the time.
Even the most spontaneous sorts were 80 per cent predictable.
Professor Barbasi said: ‘We are far more predictable than we actually think.
‘You have a regular schedule but think there are people out there who are less regular and are very spontaneous.
‘What we are finding is there aren’t those spontaneous people out there. Each of us are very regular and that regularity makes us very predictable.
‘It seems to be something innate to how we are and how we like to behave.
I wonder what my predictability score would be. This weekend I went for the first time to the Asian Art Museum in San Francisco. I try to go somewhere I’ve never been as often as possible. Life is short.
