I’ve been trying to think of an appropriate metaphor to explain the importance of test strips with respect to diabetes management but my mind keeps going back to the plane crash sequence from Die Hard 2. In it, the bad guys recalibrate sea level for one of the plane’s automated landing programs by 200 feet. Because the weather is bad, the pilots have to rely on their technology to land safely. But, since the bad guys tinkered with the system, when the plane thinks it’s at 200 feet, it’s actually crashing into the runway.
This is incredibly morbid and hyperbolic, but if you stay with me I’ll bring this back around.
The key here is that the pilots had to trust in the tools at their disposal, namely the computer system tasked with landing the plane in inclement weather. The computer system relied first and foremost on the altitude of the plane to govern the entire landing sequence. But because that core piece of data was flawed every action taken based on that number was not going to succeed. (I hope you forgive the casual language of ‘not succeeding, even if it’s just a movie, a plane crash is serious business.)
If you ignore the Hollywood factor, the basic premise still holds: actions informed and influenced by a flawed piece of data will not succeed as intended.
