LinkedIn's study A causal test of the strength of weak ties shows that weak ties - casual acquaintances versus close friendships - provide the most useful connections in job hunts.
This confirms Mark Granovetter's landmark 1973 study The Strength of Weak Ties
As LinkedIn's article points out, Granovetter's study was conducted well before the era of big data and his surveys often had less than 100 respondents.
LinkedIn's study was massive. Key quote from their article:
"Digging deep this time, Rajkumar and colleagues tracked the modern-day connection-making patterns — and job-hunt outcomes — of 20 million LinkedIn members. The research was conducted on data from 2015 and 2019."
The reason weak ties turn out to provide the most help for job hunters is nicely explained in the LinkedIn article:
"When we connect with so-called weak ties — people we know only slightly — we gain access to job networks that stretch into unexpected areas. That lets us find people and opportunities we otherwise wouldn't know about.
This is the magic of weak ties," Rajkumar says. "They bridge information flows. They help us navigate large spans of the labor market efficiently." By contrast, our best friends' contacts are so similar to ours that they don't help much; they're redundant."
So what has this got to do with coworking?

The answer is simple.
As we pointed out a decade ago in our article Coworking Strengthens Weak Ties, belonging to a coworking space increases the size and usefulness of members' weak tie business networks.
We also found that weak tie networks don't just improve job hunting outcomes. Weak ties also improve business development outcomes.
This is especially important for independent workers (freelancers, etc.). who can leverage their coworking weak ties to win new projects and business.
Like Granovetter's studies, our first studies on weak ties and coworking were qualitative and had relatively small sample sizes.
But since 2012, we've surveyed thousands of coworking members and interviewed hundreds more on this topic. And our findings have been consistent - coworking increases the weak tie networks of members, and that improves their business development outcomes.
LinkedIn's weak tie study doesn't directly confirm our work on weak ties and coworking. But it reinforce our study's findings by illustrating the power of weak ties.
