Surprising someone -- whether it's by a joke or via a gasp-inducing plot twist of a book or movie -- can not only create a memorable experience, but also become a powerful tool for social influence, according to a study.

Surprises are memorable, able to garner attention and arouse emotion, but a less heralded effect is that they can serve to shift attitudes and provide an avenue to influence people, said Jeffrey Loewenstein, Professor at the Gies College of Business at the University of Illinois.

While many people think of surprise as an emotional expression, the study, published in the journal Topics in Cognitive Science, showed that surprise not only generates an emotional reaction, but is also "a push to learn, and an experience that people get excited to share with others".

"Put those things together and surprise becomes a powerful tool for social influence," Loewenstein said.

Moreover, surprise not only has individual effects on beliefs and attitudes, but also "collective effects on the content of culture", the researchers said.

"We're in an information-rich environment where our primary challenge is how to identify what to pay attention to. And surprise, which shatters expectations, is a signal that says 'Hey! Pay attention!'," the researchers added.

That surprise can lead to changing attitude and shifting preconceptions.

"Critically, there is a second effect because you are not only making one person more open, you are also making them your ambassador. You are likely to generate word of mouth as they share the surprising experience with others. Surprise is a force multiplier for communication," Loewenstein said.

What generates surprise need not be accidental or random. According to Loewenstein, there are predictable methods or patterns, such as the repetition-break structure, for generating surprise.

"Crafting surprises is something everyone can learn to do, and they will be more influential if they do," he noted.

Ottawa (PTI): Three Indian nationals have been arrested by Canadian police on an anti-extortion patrol and charged after bullets were fired at a home.

Harjot Singh (21), Taranveer Singh (19) and Dayajeet Singh Billing (21) face one count each of discharging a firearm, and all have been remanded in custody until Thursday, the Surrey Police Service (SPS) said in a statement on Monday.

The suspects were arrested by patrol officers after an early morning report of shots fired and a small fire outside a home in Surrey's Crescent Beach neighbourhood, the LakelandToday reported.

On February 1, 2026, the SPS members were patrolling in Surrey’s Crescent Beach neighbourhood when reports came in of shots being fired and a small fire outside a residence near Crescent Road and 132 Street.

The three accused were arrested by SPS officers a short time later, the statement said.

SPS’s Major Crime Section took over the investigation, and the three men have now been charged with Criminal Code offences, it said.

All three have been charged with one count each of discharging a firearm into a place contrary to section 244.2(1)(a) of the Criminal Code.

The investigation is ongoing, and additional charges may be forthcoming. All three have been remanded in custody until February 5, 2026.

The SPS has confirmed they are all foreign nationals and has engaged the Canada Border Services Agency, it said.

One of the suspects suffered injuries, including two black eyes, the media report said.

Surrey police Staff Sgt. Lindsey Houghton said on Monday that the suspect had refused to comply with instructions to get out of the ride-share vehicle and started to "actively resist."

"As we were trained, he was taken to the ground and safely handcuffed," said Houghton.

A second suspect with a black eye was also injured in the arrest after refusing to comply, Houghton said.

The arresting officers were part of Project Assurance, an initiative that patrols neighbourhoods that have been targeted by extortion violence.

Houghton said the Canada Border Services Agency (CBSA) is also involved because the men are foreign nationals, and the trio may face additional charges.

It's not clear if the men are in the country on tourist visas, a study permit, or a work permit, but Houghton said CBSA has started its own investigation into the men's status.

Surrey has seen a number of shootings at homes and businesses over the last several months, but there's been an escalation since the new year.
