Before I read the article, I like to know who wrote it to understand whether I should spend or waste my time reading the article.

After a bit of digging it turned out the author isn't lying. There actually is a contest for forecasters and of those who participated, he was consistently in relatively high positions. See 2022:

At the same time, he is the CEO of Rethin Priorities think tank which seems to be excellent work for the society at large:

So I'm bookmarking this article and will read it during my reading session today.

Thanks this is helpful.
