How does bias distort our thinking, our listening, our beliefs... and even our search results? How can we fight it? On this week's show, TED speakers explore ideas about the unconscious biases that shape us.

Yassmin Abdel-Magied says people often make assumptions about her because she wears a hijab. She challenges people to recognize this as an unconscious bias -- and learn to look a little deeper.

Why do many people dismiss issues like climate change, despite strong scientific evidence?  Climatologist J. Marshall Shepherd examines how different forms of bias shape how we perceive science.

We think of search engines as unbiased sources of information. But they're not -- and they can be manipulated. Andreas Ekstr�m asks: who should hold the burden of addressing bias in search engines?

Experimental psychologist Tony Salvador says we often hear only what we want to hear. He asks us to move beyond selective listening and be open to hearing all ideas - even ones we don't agree with.
