Or, more precisely, the pretense that it is important is fake. In my experience, during the Winter, TV meteorologists report the wind chill factor about twice as often as the actual temperature and often use fake synonyms such as "feels like temperature."
From Wikipedia,
https://en.wikipedia.org/wiki/Wind_chill , "Wind-chill or windchill, (popularly wind chill factor) is the perceived decrease in air temperature felt by the body on exposed skin due to the flow of air."
That would be useful information, if you were naked outdoors. If you wear clothes, wind chill is nearly useless. If you want to estimate the cost of heating your house, wind chill is completely useless.
The reporting of wind chill factor is detrimental to society because:
1. It adulterates and obfuscates useful information such as the actual temperature and wind velocity. If the viewer isn't alert, he or she may mistake the reported wind chill factor for the actual temperature and make bad decisions. After all, wind chill is reported much more often than temperature.
2. The reporting of wind chill factor needlessly causes anxiety in many people because they are too stupid to know that it is unimportant.
If TV meteorologists were moral, they would report the temperature and wind velocity instead of the wind chill factor and give the formula and URL of a website for calculating the wind chill factor in a little banner across the bottom of the screen:

In summary, TV meteorologists are moral scum, even the beautiful weather girls.
