Two-thirds of the public would walk away if they saw a group of teenagers drinking and verbally abusing passers-by in the street.
A survey by YouGov found only 6% of the 1,784 people questioned said they would definitely intervene.
When Jennifer Ospici found two men burgling her house after she returned from a shopping trip, she decided to take action.
She told BBC Breakfast how, without hesitation, she disabled their getaway vehicle, "biffed them" with an antique rifle, and chased them out of the house.
