> I'm not aware that the WHO ever claimed simultaneously contradictory things.
Whether they did or not is almost irrelevant: information doesn't reach humans instantaneously, it takes time to propagate through channels with varying latency, it gets amplified/muted depending on media bias, people generally have things going on in life other than staying glued to new sources, etc.
If you take a cross sample you're guaranteed to observe contradictory "parallel" information even if the source is serially consistent.
What's the point of reading something while drinking my coffee quietly?
When I'm drinking my coffee I focus on enjoying the palate, when I'm reading I am laser-focused on processing and retaining information.
Multitasking prevents me from attaining the full benefits of these exquisite activities. If need a mindless task while I'm sipping my morning brew I can always count primes backwards or stare at the other hipster in the coffee shop.
