More like biased against high risk, low reward constructions. What is considered a low risk with a potential high reward in some places has the inverse in other places.
For example, taking a high risk of attempting to create a unicorn startup for the low reward of having more money isn't really worth it here. That's because the barrier at which point 'more money' makes your life 'better' is much lower. Same goes for prestige, it doesn't really get you all that much here.
Together, that means that taking larger risks doesn't really have a lot of benefits in general, unless you personally enjoy it.
This is different form the need to have a 'big' change requiring a 'big' risk in order to make your life measurably better (monetarily, prestige, perceived power, or otherwise).
There are endeavours that pose significant risk, but have a significant reward to match; think ITER and CERN; it is a considerable effort and monetary investment without knowing what the true outcome will be. All you know ahead of time is that something will come out of it. (while those two aren't exactly comparable; a single-purpose project vs. an organisation with multiple projects; it's about the concept of risk, investment and possible outcomes or returns)
Say a particle accelerator take a lot of time, labour and money and can be used to make discoveries, but you don't know what discoveries. That means you have a huge investment but no guarantee that you will be able to produce something that has the value of the investment (or more). But there is the chance of significant scientific discovery, which makes it a project that countries are willing to take the risk for.
Expanding on my own word salad: perhaps personally I'd say that in my environment collecting money or 'stuff' in itself isn't seen as valuable, but being able to maintain a good life and have a fulfilling life is. At the same time, in a larger context, things like discovery, exploration and research are valued as well, but boasting or broadcasting about it isn't seen as very valuable. I suppose that also makes for an environment where space exploration is seen as a good thing but ironically without a big PR machine it can't be funded. It's like having a goal without the means.
