Google CFO Ruth Porat says you shouldn't hire women just because it's 'the right thing to do'

Google and Alphabet CFO Ruth Porat wants more women in the workplace because it's good for the bottom line.

Speaking at the Vanity Fair New Establishment Summit in San Francisco on Wednesday, Porat said, "This is not just the right thing to do socially. It's the right thing to do for your business."

The research backs it up. CNET points to a Lehman Brothers survey of 100 teams, which "found that 'gender balanced' teams were most likely to experiment, be creative, share knowledge, and fulfill tasks."

A second study in Institut National de la Statistique et des Etudes Economiques in 2009 "found that technical work teams with women were better at staying on schedule and had lower project costs," CNET reports.

Furthermore, research shows having more women in leadership roles is linked with better financial performance. On average, Fortune 500 companies with the highest percentage of female board directors significantly outperformed companies with the lowest female representation on return on equity, return on sales, and return on invested capital, according to the research group Catalyst.

Earlier this year, Google released a diversity report that showed women comprise only 30% of the company's workers and just 22% of its leadership team. Meanwhile, women hold less than one in five tech roles at the search giant.

Porat isn't alone in her charge to bring more women into the mix, but she's skeptical of the solutions proposed by Facebook COO Sheryl Sandberg in her bestselling book "Lean In."

"If the door is nailed shut and you're 'Leaning In,' you're just going to get bruised and battered," Porat said at the summit.
