Changing public attitudes is a three-part process. First, people need to be taught to recognize the warning signals. Second, they need to get beyond their misgivings. Finally, they need the tools to intervene properly.
Step one is relatively easy. Most people know what to look for: unexplained injuries (bruises, lacerations, fractures); behavioural changes (withdrawal, fearfulness, depression); unusual financial transactions (large cash withdrawals, sale of property, liquidations of assets).
Step two becomes easy when you realize what's holding you back is often misinformation. Alan Berkowitz, an American psychologist specializing in bystander behaviour pointed to three common beliefs - all wrong - that immobilize people.
