Study shows 38 percent of Americans fear crowded events due to terrorism threats

HOUSTON -- Does fear have you rethinking your summer plans?  With terror attacks becoming somewhat of a norm, many Americans are thinking twice before hanging out in large crowds.

Gallup World Poll says 38 percent of Americans fear a terrorist attack will happen at events with thousands of people in attendance.

Gallup conducted the poll in wake of the Ariana Grande concert attack on May 22, and the attack on the London Bridge on June 3.

Thirty-eight percent is the highest since 9/11, 16 years ago, when only 32 percent of Americans reported a fear of terrorism.

But should we let fear run our lives?

"The more you avoid a situation that you're fearful of, often times the bigger the fear becomes," said Dr. Wendy Campbell, a psychotherapist.
