Sentimental value is driving the killer to extreme measures violent, and they won't stop until they get one of Bridget's arts in their hands.

Blair: Apparently, all plain air paintings completed in late 1883 must contain some residual volcanic ash.
Mercer: Makes sense. Krakatoa erupted August 1883. A cloud of volcanic ash went from Indonesia all the way to Europe.
Rose: And the appraisers didn't find volcanic ash in the orchard.
Blair: Even though the results aren't conclusive ...
Rose: You're concerned your painting is a copy.
Blair: A fake, just like my marriage.

Doctor Atwood's testimony appeared fair and unbiased. The problem is with paid experts like Dr Atwood, that's never the case. Introducing money creates bias. I wanted to better understand how this bias works, so I conducted an experiment where I paid experts to give their opinions on a fictional case, a slip and fall in a hotel. All of them had the same facts in the case; the only difference was which side the person was on paying them. Almost all the experts argued for the side paying them. If the defense paid, the expert's opinion sided with the defense. Same for the plaintiff. That's bias.

People tend to say it's only a few bad apples, but those bad apples spoil the whole bunch.

Camille: How did you get that?
Mercer: Misdirected attention.
Kylie: Also known as Kylie's got skills.

Mercer: What's going on?
Marisa: We got here a few hours too late. There was a note.
Mercer: Was it suicide?
Marisa: I'm so sorry, Alec. We have a team in there searching the entire place for additional information. We're gonna figure this out.
Mercer: He was our best chance of finding out the truth. Now he's gone?

Camille: I could really use your help to figure this out. How does a trip to Vegas sound?
Mercer: Intriguing, but isn't there a whole security squad devoted to this type of thing?
Camille: Yes, but they can't see the things that you can.
Mercer: I can't say gambling fraud is my typical wheelhouse.
Camille: I know, but this isn't just about a game, Alec. There's a lot at stake here.

Given your guilty fidgeting, Keith's hostility, and Ted's inability to look away from you, I'm pretty sure you and Ted had an affair. Long term? You ended it. You and Keith stayed together, but it's still a source of tension in your marriage.

Zero Sum bias is the misbelief that nonmaterial resources like love, respect, even good grades are finite. Such that if one person wins, then another one has to lose. The worst part about Zero-Sum bias is that it can make a situation where everyone could win into a cutthroat competition, making win-win into win-lose.

Trey: Stop, or I'll shoot her
Mercer: I just came to talk. I feel like what's happening here is my fault. I'd have gotten here sooner, but you know, there was so much snow.
Trey: Snow? It's not snowing.
Mercer: Sorry, Eddie. I stand corrected.
Trey: My name is Trey.
Rose: What is he doing?
Marisa: He's using absurdism, saying weird things to force Trey to correct him and ground himself in reality.

Trey: Look, Mrs. Moore has worked at our house for as long as I can remember. Veronica and I practically grew up together. She may not be my sister, but she's still family.
Mercer: Pseudo-family bond.
Trey: Mr. Moore, sounds like my dad really hurt you, but let us help.

Six million car accidents per year. The chances of dying while going to see a plane crash are 1000% greater than dying in one.

The Irrational Quotes

Marisa: That ability you have to completely divorce emotion from reason is both why I married you and...
Mercer: ... why you're longer married to me.

People are irrational. But predictably so. They're more afraid of flying than driving, and the fact is, driving is much more dangerous. We know we should eat healthy food, but then we give in to temptation. Buy things we will never, ever use. We assume people are making rational decisions, weighing the pros and cons. For most of the time, we're not. Instead, we rely on instincts, which are almost always wrong. Sometimes, dangerously wrong. One error in judgment leads to another.
