Is Iceland in danger of potential inbreeding? The entire country only has a population of a little over 300,000 so will they soon risk inbreeding?

300,000 is more than enough genetic variation to sustain a healthy population. Human mobility in the past has been restricted and humans generally ended up marrying locally amongst their fellow inhabitants (With far fewer than 300,000 people) and they turned out fine.

as above stated also it's interesting to note inbreeding doesn't mean the child will turn out badly it just means a significantly higher chance of mutations and health problems / defects the children have a chance of being normal.

As long as the population remains that strong there is very little chance of imbreeding / lack of genetic variation

You see the reason some countries allow marrying of a second cousins is because the birth defect rates are very low since they are far enough apart.
the chance of a baby with a birth defect with a second cousin is 2/3%

Given that there are 300,000 people it's unlikely that at any point in time everyone will be more then second cousins (first cousins or close relatives etc)

Therefore there is no risk.

i wouldn't say its a danger to society or anything but there is an app there specifically to avoid accidental incest. so they at least have to stay on their toes so they don't unintentionally pork a relative

inbreeding can mean two things actually, granted there's the chance of incest, but inbreeding also could mean the possibility of mix racing. so, with that stated, with that few there's a chance there could begin the concept of mix racing, but there's been mix racing for thousands of years now. but as for the first option of breeding among the same "gene pool" as long as it's spaced to third and fourth cousins there's a lower chance rate of having mutations, but not uncommon. siblings, first and second cousins not an easy escape moment. there are many cases of "locked indoors and hidden away" in the England of old where first cousins had children, or siblings. but, even as we near 8 billion people on this planet, we're still only separated so evenly, the chances that we are related are slim, but it's not unheard of. we're still a genetic code after all.

I thought I heard that they had some dating app that let's them tell if they are too closely related before meeting up

300,000 people? I think everyone can run out of second cousins before the hat comes around again. Plus, they can always export their women. I hear there's a market.

Relatedly, I had heard recently that, in the long term, inbreeding is actually 'good' for a population, as it weeds out negative mutations (dead babies), but it's hard on people in the short term because of (dead babies).

You could start a genetically stable colony with 14,000 people. Iceland has more than enough people.

When you're considered a second cousin or further, that's barely being related to someone.

Just don't be like a Habsburg and marry your aunt.
