When traveling through an airport and required to navigate repetitive security sectors, does it make you feel safer or more frustrated? What deficiencies exist in the first round of screening that require a second or third round of reexamination?

Multiple checks are embraced in context. Headed to surgery, multiple confirmations of the patient’s identity and procedure are appreciated. Being asked if you have accepted an item from a stranger in the five minutes between security stations brings up questions about the quality of the previous screening phases.

How might we balance providing security while establishing trust in the process?
