fraught

今日取り上げるNUDGE by R. H.Thaler and C. R. Susteinに出てきた "fraught" もこれまでにもどこかで何度か見ている気がしますが、意味を覚えていない単語です。
Often market competition will do a lot of good. But in some cases, companies have a strong incentive to cater to people's frailties and to exploit them.
Notice first that many insurance products have all of the fraught features that we have sketched. The benefits from holding the insurance are delayed, the probability of having a claim is hard to analyze, consumers do not get useful feedback on whether they are getting a good return on their insurance purchases, and the mapping from what they are buying to what they are getting can be ambiguous. But the insurance market is competitive, so a natural question to ask is whether market forces can be relied upon to "solve" the problem of fraught choices.

Tips: The modern definition of fraught is derived from the 14th century English fraught, “to load with cargo." For a memory trick, note how fraught is similar in spelling and sound to freight. Now, in line with the idea of loading something with cargo, think of a freight train fraught (overloaded) with cargo, but think of emotional cargo or baggage--it should be used for intangibles (fraught with anxiety, fraught with mistakes) and not tangibles. Fraught can also mean "uneasy, charged, or stressed." Think of the stress of having to hold something heavy or being overloaded with something. Fraught is also similar in meaning and application to rife.
