To accomplish this, the group spent a year writing at rural properties owned by Sanderson and bassist Brad Walst.

[8] The group also supported Avenged Sevenfold and Prophets of Rage on the End of the World tour that same year.

[14] On November 13, 2018, the band released the album's opening track, "Right Left Wrong", as the third single for radio airplay.

He concluded, "It's what sets this record apart from other alt-rock outfits right now, whereas much of their peers are focusing on feel-good party anthems, Three Days Grace give us a masterclass in coming to terms with the well of emotions that lay inside of us.

"[17] Kaj Roth of Melodic gave a mixed review of the album stating, "Outsider sounds pretty much like a typical Three Days Grace album but it's just not as great as Human or their early stuff, it's well produced and they show no signs of selling out but most of these songs won't make it onto a best of with this band.

"[18] Joshua Leep of Salute also gave a mixed review of the album remarking, "teens and young adults will definitely be able to grasp pretty quickly.

"[19] Simon K of Sputnikmusic praised the tracks, "Villain I'm Not", "Right Left Wrong" and "The Mountain" for its "infectious chorus."

However, he criticized the lack of change in their sound, but complimented the "tight rhythm of 'Strange Days' or sombre synth saturation of 'Love Me or Leave Me'."

He ended off remarking, "Outsider lacks is that one track to grab onto; there's nothing standout here, nothing that will justify you coming back for a second helping.
