Juries in a civil trial are the biggest crapshoot in the entire legal industry.
A settlement is based on negotiation, and the final number is the closest to fair that everyone with a stake in the outcome can agree to. One side makes an offer, the other side a counter-offer, back and forth. The parties both have to agree, both of their counsels have to agree, and the judge has to agree. Rational decisions are the rule.
The members of jury, by legal requirement, are completely disinterested. Send the wronged party packing without so much as a nickel towards their legal bills? Maybe somebody on that jury got dumped by a guy who looks like the plantiff. Award a record-breaking punative and compensatory fine against the defendant? Maybe that company laid off once somebody's brother-in-law and he beat up a juror's sister. Wildcards are the rule.
Jury trials are the last resort, a kind of systematic threat, designed to guide both sides towards a settlement and get on with life.
