Insight, 7.30pm, SBS Tonight Jenny Brockie, pictured, and her full house of considered opinion- makers tackle the issue of finding courage. Why do some of us step up to the plate when circumstances requiring heroism present themselves while others remain frozen on the sidelines? Are we born with courage or can it be learned? Meet a courageous young man who jumped 14m off a Grafton bridge to help a woman who had left behind a neatly folded jumper and a suicide note. He saw her floating facedown in the river and almost instantly jumped to her rescue. What was he thinking? How long did he consider his response? He says his action was pure instinct. We also hear from a woman who survived a light- plane crash but risked her life to go back in to save others, knowing the plane could explode at any second. How does she cope with the full- thickness burns to 67 per cent of her body that resulted from her act of courage? Is empathy hard- wired into us, as professor Ladd Wheeler suggests? If that’s true, how do we explain the bystander effect, a well- known syndrome characterised by fear and inaction. A fascinating Insight lives up to the program’s name. 20 to 1, 9.30pm, Nine The eternal Bert Newton, filmed generally behind a tonne of foundation and at some distance, will take us on a merry chase through Australia’s 20 greatest scandals, rated in importance by redundant Nine Network tea ladies and the show’s producers.
