It has been a singularly challenging year for the motion picture industry, which makes the annual Behavioural Economics Oscars even more meaningful than they have been in the past (hard as that may be to believe).

This year, the awards committee for the Becons, as they are known for short, has decided to expand the set of eligible winners, including not only feature-length films released in theatres in 2020, but all films and television series that have provided delight, consolation and joy as well as valuable lessons amid the pandemic.

Best actor: Behavioural economists have devoted a lot of attention to 'reactance,' which means that people dislike being ordered around, and will sometimes rebel against a mandate or a prohibition simply because they want to assert their own agency. If an employer or a public official tells you that you can't do something, you might want to do it just for that reason.

The movie 'Mank' is about two mysteries: Who really wrote 'Citizen Kane,' often said to be the greatest film ever made - Orson Welles, the Boy Genius, or Herman Mankiewicz, the grizzled, alcoholic screenwriter? And what were the origins of that epic tale?

Propelled by Gary Oldman in the title role as Mankiewicz, 'Mank' gives intriguing answers to both questions. But more than that, Oldman offers a brilliant (and timely) portrayal of reactance against injustice and mandates, both in politics and in personal life. In 1941, Mank shared the Oscar for 'Citizen Kane' with Welles, but in 2020 Oldman gets the Becon, and he doesn't have to share it.

Best actress: One of the most robust findings in behavioural science is called "anchoring," which occurs when an initial number sticks in people's minds and has an outsized influence on their ultimate judgments. Smart negotiators are well aware of the power of anchors; if they can start with a high number or low number, depending on their goals, they can get a bargaining advantage.

'Younger' is a television series about Liza Miller, a divorced woman in her 40s who faces job discrimination when she tries to re-enter the job market. Her best friend has a solution. Liza should get a new haircut, act like a kid and pretend to be in her 20s. She does. As usual, the anchor works: Because people are told that she's in her 20s, they tend to believe it.

Sutton Foster, the star of the show, is convincing as a forty-something, a twenty-something and as a forty-something playing a twenty-something. She's both hilarious and moving - not least when she falls in love (twice). The Becon isn't an anchor, but it's awfully heavy, and Foster gets to take it home.

Best director: In recent years, behavioural economists have focused on the question of 'noise': variability in judgments that are not supposed to vary. One judge might sentence a criminal defendant to a year in prison, whereas another judge, seeing an identical defendant, might decide in favour of probation. That's noise.

Some of the most interesting work on noise explores unique decisions. If a company is deciding whether to open an office in another city, or if a nation is deciding whether to go to war, small variations in circumstances can make all the difference: whether it is a sunny day, for example, or whether a particular adviser decided to speak up at a crucial moment.

'Tenet,' a science-fiction thriller, is a dazzling exploration of noise – of how history's arc can be a product of seemingly small interventions and variations. Christopher Nolan, the brilliant director, juggles a thousand balls, dropping not a single one. For that he deserves the Becon.

Best film: "Desirability bias" means, in brief, that people believe what they want to believe - which by itself isn't exactly shocking, but which explains all sorts of things, including social division, polarization and the power of misinformation.

'Messiah,' a television series, is a thriller about a mysterious man from the Middle East played by Mehdi Dehbi who may be a trickster and may be the Messiah, and who is attracting converts all over the world. What if Jesus appeared today? The maybe Messiah is investigated by a CIA officer, played by the amazing Michelle Monaghan.

The series investigates desirability bias, and its role in faith - and in the absence of faith. It constantly asks: What do you want to believe? 'Messiah' is a miracle, and it wins the Becon. Amen. (Bloomberg)
