IDK if they still cheat, but definitely the Finnish results are wrong. Obviously 23andme's algorithms suck. Bad algorithms are not surprising and figures more the recent situation in population genetics. The results are based on a few basic rules and the historical reality is still too complex. Researchers have not yet found how to figure the reality.

Some ethnicities are "easy" and someones are not. 23andme, among a few others, try to be very scientific (forgetting cheating), but actually they are not deep enough in this science to be able to mirror the reality. If they would have stayed with basics using allele distributions and genetic drift, but playing with autosomal haplotypes was not a good idea.

I wonder about that. Considering how badly they pick out some ethnicities, I wouldn't be surprised if every single "jewish" result was off. I know that FTDna assigns it to almost half of all its "white" test takers, european and americans both.
If you guys want to see some really bad estimates, check out this post of mine on Anthrogenica! https://anthrogenica.com/showthread....l=1#post787884

They definitely do. The commercial companies tell you what you want to hear. For instance, my name is Irish but of Norman or cambro-norman ancestry. I am about half Celtic but there is no one Celtic cluster e.g. Gaelic and Welsh are different. Anyway, based on my name AncestryDNA and LivingDNA they said I was half 'Irish'
but G25 calls it England_IA which nowadays would be more Welsh or native Brittonic. Also, MyDNAPortal recognizes that Celtic part as Welsh too etc...
There was poster here called NeonKnight or BritishKnight who told me , before genetic testing, that I look Brittonic and Xenophobic Prussian said I look Welsh/Cornish/Devonshire British etc...in other words I don't look particularly 'Irish' either.
Basically, it is bad for capitalism to tell most people the truth as it might shatter their delusional preconceptions about themselves.
If they are a mixture of disparate ethnicities, say Italian and Irish then sure, but a mix of NW European ethnicities (in the case of many White Americans) that are already somewhat related anyway is not really a mutt to me
