I would have thought the there were a Bostrom-Sandberg effect, specially since Sweden doesn't have such a big population. However, by looking at the WVS graphic it's hard to say rational self-expressing values wouldn't be expected to correlate with transhuman values. But, yes, probably the egalitarian sentiment would be a factor against transhumanism, I've heard transhumanists there complaining about that.

Thank you for your input, you were the first to present a counterevidence to my assumption. Those things might be more valuable than you think in this case.
