Generally, when a couple is trying to have a baby, the focus is put on the woman’s health. But today, more and more, fertility specialists are learning that the male’s contribution is almost as important, and male health as a consequence just as impactful.

Why Diversity Is More Important Than Having a Meritocracy

Look at Wall Street in 2008, and the White House right now. Diversity—of people and cognitive perspectives—is crucial for avoiding failure.

We need to rethink our diversity strategy, says Sallie Krawcheck. What we've been trying for the last decade hasn't been working, but what exactly is the problem? Research reveals that diversity is actually worse in meritocracies. Managers—and particularly middle managers, Krawcheck points out—fall into the cognitive trap of hiring people who "remind me of a young me" (i.e. look like them and think like them) instead of more cognitively diverse people who would bring a missing skill set to a team. This is as important now, under the almost all-white male Trump administration, as it was in the 2008 Financial Crash. Wall Street is one of the most homogenous institutions in America, and Krawcheck has no doubt that having a more diverse set of minds in finance would have lessened the severity of the global crash. In addition, risk-taking and the poor decision making that results can be tracked to fluctuations in one hormone: testosterone. Whether it's the housing bubble, America's healthcare, or foreign policy, these are mistakes that affect millions of lives. As a CEO, Krawcheck's approach and advice on diversity is changing. The current strategy has been a failure, but what if companies paid their managers, in part, based on the diversity of their hires? What if we thought of diversity as more important than meritocracy? Sallie Krawcheck is the author of Own It: The Power of Women at Work.

What the Length of Your Fingers Say About Your Personality

Your ring-to-index finger ratio can tell a lot about what you’re good at and even what mental disorders you are prone to. 

 

Hands pressed together.

The eyes may be the window to the soul, but the hands can tell you a lot about a person too. Whether they are calloused for instance, or cotton soft. The fingers in particular can give you further insights. A collaborative study conducted by Oxford and Northumbria researchers in the UK, found that differences in the lengths of certain fingers indicated whether a person tended to be more promiscuous or monogamous by nature. The secret lies with the ring finger in comparison to the index.
