Following Red Velvet's third concert "La Rouge" in November 2019, SM Entertainment revealed two teaser posters on social media at 00:00 on December 12 that year, along with an official press release that confirmed "Finale" would conclude Red Velvet's "Music Festival" trilogy throughout 2019. Two days later, the first batch of teaser photographs were posted on the group's official social media accounts, including "Psycho" as the lead single for this release. The song's instrumental intro was also revealed on their official Instagram account before a 17-second video teaser for the song was uploaded to the official SM Town YouTube channel. The music video was released the following day.
"Psycho" was written by American record producer Andrew Scott, Korean producer EJAE, and their frequent Swedish collaborator Cazzi Opeia during a 2018 songwriting camp in Seoul, South Korea. Following a conversation between the three composers about a breakup in which "being heartbroken is almost like feeling psycho", they started working the idea into a song. Having acknowledged Red Velvet's dual sonic concepts, in which "Red" refers to the group's mild and vibrant image, and "Velvet" refers to their smooth R&B side, Scott wanted to "blend the two" concepts together. Opeia recorded a demo version in English that was leaked on the Internet weeks before the song's release; songwriter Kenzie the rewrote the lyrics in Korean with additional arrangement from producer Druski and Yoo Young-jin, the latter of whom co-produced the group's previous single "Bad Boy" in 2018.
Musically, "Psycho" has been described as an up-tempo urban song; Tamar Herman of "Billboard" described it as an R&B-pop track with future bass, a "grandiose operatic" instrumental intro with "dramatic" pizzicato strings, "classical" chords and trap beats, squelching synthesizers, which made it the group's seventh single to fall under the "Velvet" concept. According to Scott, the chorus contains the syncopation of hi-hats that is combined with the drum line to maintain the song's pace. It was composed in the key of Eb major with a tempo of 140 beats per minute. The group's vocals span two octaves, from the low note of G3 to the high-note of G5. A slightly different version of the song was used for the music video; the chorus has an additional synth line and the pre-chorus included a string melody, elements that were omitted from the digital and streaming version. The song's lyrics tell the story of a relationship that is "full of ups and downs" in which a couple "fights so much that they appear crazy in the eyes of others but are nonetheless meant for each other" and eventually assure the listener "we're gonna be alright".
"Psycho" debuted at number two on South Korea's Gaon Digital Chart for the period December 22–28, 2019, the year's final chart; rapper Changmo's "Meteor" blocked it from reaching number one for three consecutive weeks. The song entered the Monthly Digital Chart for December at number 31 and peaked at number three on the January 2020 issue. It topped the Gaon Download Chart for two weeks, giving the group their sixth number-one song on the chart, and peaked at number two for two weeks on the component Streaming Chart. The song entered the "Billboard" K-Pop Hot 100 at number nine on the chart issue dated December 28, 2019.
On the chart issue dated January 1, 2020, "Psycho" peaked at number two, where it remained for two consecutive weeks. In November 2020, the song received platinum certification from the Korea Music Content Association for surpassing 100 million streams. "Psycho" was the ninth-best performing single of 2020 on Gaon's Year-end Digital Chart, and the only one by an idol group to appear in the top ten.
On the week of January 4, 2020, "Psycho" debuted at number one on the US "Billboard" World Digital Songs Chart, giving Red Velvet their second US number-one song following their 2018 single "RBB (Really Bad Boy)". This made them one of the nine K-pop artists to top the chart more than once, and the fourth girl group to do this. Moreover, "Psycho" became Red Velvet's 16th top-ten entry, thus tying with 2NE1 as the South Korean girl groups with the most top-ten entries on the chart. The song also became Red Velvet's second entry on the New Zealand Hot Singles chart after "Zimzalabim", entering at number 10 for the week of December 30, 2019. It also debuted at number 99 on the UK Singles Downloads Chart, where it spent one week, becoming their first song to appear on a UK component chart.
Red Velvet delivered their first live performance of "Psycho" at the "ReVe Festival FINALE Party" on December 22, 2019, which premiered exclusively on V Live. The group's attendance at the annual "SBS Gayo Daejeon" for the debut television performance of the single was confirmed on 25 December but vocalist Wendy was injured during rehearsals and a pre-recorded performance was aired instead. The group subsequently performed as a quartet, and covered all of Wendy's parts, at the 29th Seoul Music Awards on January 30, 2020. "Psycho" was also included in Red Velvet's three-song set for the "SMTOWN Live Culture Humanity" online live concert on January 1, 2021.
Following its initial release, music critics gave "Psycho" positive reviews. Tamar Herman of "Billboard" magazine said the track is "smooth and sultry in its delivery". In an individual song review, writer Kim Do-hyun of "IZM" said the track is "an upgraded version" of "Bad Boy" and praised the balancing of "a great melody, interesting themes and performance" that crafted "a good song" and rated it three-and-a-half stars out of five. Refinery29's Natalie Morin wrote the song has "all the charm and swagger of ...'Bad Boy' but with an updated, sophisticated glow". In an interview with the song's producer in February 2020, writer Yim Hyun-su of "The Korea Herald" described "Psycho" as a "catchy earworm" and said Red Velvet "shows no signs of stopping anytime soon".
Despite being released in December, "Psycho" appeared on several year-end music lists as one of the best K-pop releases of 2019. "Billboard" ranked it at number 18 on their critics-pick list. "L'Officiel Malaysia" cited "Psycho" as one of 14 definitive K-pop songs of 2019 and called it a "go-to track to sing in the shower". Online magazine "Whole Tone" described "Psycho" as "the track that has created the most impressive spot among K-pop works released over the past year" and put it at number one on their list. "Psycho" was also placed at number one on "Paper's" list "The 40 Best K-Pop Songs of 2020".
Despite Red Velvet not attending nor performing on any television music show, "Psycho" won nine music-show trophies by January 2020, became the group's second most-awarded title track in a tie with their 2017 single "Rookie", and was their first song to achieve triple-crown status on all three national television channels, namely "Music Bank", "Show! Music Core" and "Inkigayo". The song also achieved two consecutive Melon Weekly Popularity Awards.
The accompanying music video for "Psycho" was directed by video director O, whom previously worked on the music video for "Umpah Umpah". The music video for "Psycho" was premiered on December 23, 2019, to coincide with the release of the song and that of "Finale". Prior to its premiere date, the music video was teased with a series of short videos showing each group member in a "glam" and "gothic-themed" scenario. The music video was choreographed by Mina Myoung of 1MILLION and Bailey Sok of Skeleton Crew.
The music video for "Psycho" is set in a Victorian Gothic scene. In the video, the members of Red Velvet sing about the alternating moods of a relationship. Following the music video's release, Tamar Herman of "Billboard" described it as "a modern take: on the elegant, yet festive, flair of flappers with lace and feather looks", praising the video for being "glam". Writer Morin noted the video's "gorgeous A24-esque indie classic" aesthetic. Red Velvet released a performance video for "Psycho" on January 8, 2020, and also released a live performance of the song during a fan-meeting party on January 13 of that year. On March 26, 2020, the music video for the track reached 100 million views on YouTube in 91 days and 7 hours, which is the shortest time in which a Red Velvet video had accrued that many views. By November 17, 2020, the track's music video had gained 200 million views on YouTube, which is the second of the group's videos to reach the 200 million view milestone, achieving it in 10 months and 24 days.
