Quite often I hear Finns say that German sausage is way better than Finnish sausage. They usually elaborate on this statement in a way (along the lines of "Finnish sausage is made of flour, but German sausage has a lot of meat in it") that makes it very clear that they are comparing the cheapest and the least meaty Finnish sausage with unidentified meaty German one. Often they even name the Finnish point of comparison with its colloquial name "HK Bleu" (HK Sininen lenkki, 43% meat).
The same phenomenon exists with other goods and services, but the sausage example is the most common, so I'll stick with that.
Now, when I buy a sausage in Germany it is usually worse than the ones I buy in Finland. It's hard for me to be sure that German sausages are objectively worse than Finnish ones, even as far as my own taste is concerned, because the familiarity creates a rather strong bias: in Finland I know which kinds of sausage I like the best, and I buy them; in Germany I have to select from a large number of sausages whose list of ingredients looks good, and this selection is rarely optimal.
Which makes me wonder: why doesn't this bias work for those other people? I mean, if they dislike HK Bleu, why haven't they moved on?
The ideas that come to mind are:
1. They are saying this in bad faith for some reason (why?), and are in fact well aware that they are comparing a near-lowest-quality Finnish sausage with average and above-average German sausage,
2. They are really comparing Finland's near-worst with Germany's near-worst and might actually be right.
3. They are for some reason (how?) unaware that there are lots of Finnish sausages with meat content of over 70%.
P.S. I am being unfair to HK Bleu. It is the worst sausage I tasted and didn't seem to have any meat at all, but the same manufacturer (HK) also produced a light version with only 5% of meat. I didn't really need to know that, but I decided to share the info with my readers anyway. They also produce delicious stuff that's 80% meat.
