A "study in Germany" there is no specific where, who, or what, no information is provided. Just speaking very vaguely.

No real evidence se to claim these points, no article or names could be found

Multiple references to "researchers" and "scientists" but no actual names or links

Although the blonde gene is a recessive one that doesn't mean it'll die out. Humans have been estimated to die off multiple times, whether by global warming or other means,

They had near no real information, no links, no sources, almost as if they had to make it up on the spot.

Based on the article I'm more convinced that blondes will NOT die out or become extinct within the next hundred or two hundred years.

The claim that "dyed blondes are more attractive to men" is obscene. You would have to interview ever man on the planet for that claim to be true.

The couple sources turned out to just be people, two names, and had nothing in relation to each other or really the survey except one was blonde, and another a dermatologist.

The 'study' didn't contain any real data or quotes, almost as if it was being made up or generalized.

An unkown group of people could have been interviewed, which could be 10 or 1000 people or more. This can skew a data chart heavily.

Vague statements wont trump facts, adding a couple names with no correlation to each other is not a source but more of out of context reading.

The article isn't structured too professionally either, if more time and effort was put into it, this would improve greatly.

Providing real sources and names of researches for the study would allow continuity and allow the reader to fact check for themselves going deeper into the study
