Lawyer and diversity practitioner Mariam Veiszadeh took a different approach to her TEDxSydney talk. Firstly, she asked everyone in the audience to stand up. Then, through a series of questions like ‘Did you have a job while you were at high school?’ people remained standing or sat down, giving a visual representation of unconscious bias.

Veiszadeh, who was 2016 Daily Life Woman of the Year, believes difference is the key to successful businesses and she came to her talk with the stats to back it up.

“Privilege is largely invisible to those who have it,” she says, and yet diverse companies are 35 percent more likely to have financial returns over their peers. “That glass ceiling is double glazed for a woman like me. That’s why I wear heels like I do – to break it.”
