"The infectivity [of Delta] seems to be very uneven – in some cases, one person infects a hundred people, then we have other occasions when an infected person does not infect anyone at all".
The truth is always in the anomalies. And when it comes to covid, there's plenty of anomalies. Scientists don't like anomalies, or anything that challenges the truths they have formulated. Rather than asking 'why did it not spread in that case when it did in others?', they just exclude it as anomaly. Or worse, error.
