I like risks and I like anything that will give me an adrenaline boost. I can be way impulsive or get myself into trouble without looking first, leaving everyone else to tell me, "I told you it was a bad idea."
If it was something my life totally depended on, like jumping across a wide cliff with spikes at the bottom, hell yeah I'd be scared. But little risks - like going on a big rollercoaster or trying a new food, is exciting to me.
In general, no. There has to be a reason behind the risk for me to wish to participate though, as I think taking risks just for the sake of doing so is just as stupid as refusing to even try a new shoelace color. The later is supremely dull and the former is as mentioned, stupid. Balance is key.
The answer is: it depends on the influence of other functions. IXXPs can have a strong Si or Ni tertiary, both of which are risk-aversive. And then, when auxiliaries Ne or Se are weak, the latter will arise as a silly, capricious, free-floating playfulness which is not tied down by any judging function. In this case, Si or Ni serve the inclinations of the Dominant (Ti or Fi) by helping to turn its ideas and values into rigid dogmas, displaying a mere pretense of independent certainty while secretly making of it a slave to unconscious (Si or Ni) archetypes.
