"Bad Habit" received critical acclaim. For
Billboard, Andrew Unterberger called "Bad Habit" a "perfect pop song" that displayed Lacy's "impossibly high-level" craft, adding that it "never ran out of new thrills, big and small, to get you swooning like the first time ... you heard it". It was called a "flirty standout" from
Gemini Rights and a "summer bop" by Ecleen Luzmila Caraballo of
Crack. Sam Eeckhout of
The Line of Best Fit called the song "powerful" and used the song as an example of Lacy's vocals "carry[ing]"
Gemini Rights. Cady Lang of
Time wrote that the song evoked "pure, euphoric joy" and that Lacy's songwriting had a "deeply emotional impact", while
NMEs Sam Moore called it a showcase of "Lacy's impressive vocal range, his nifty way around a guitar and his tattoo-worthy lyrics".
Mics Austin Williams praised "Bad Habit" as "immediately singable and instantly replayable", deeming its melodies "addictive" and its lyrics "endearing". For
The Guardian, Shaad D'Souza opined that it was "arguably" the best song to "spring forth from the new wave of TikTok-beloved lo-fi bedroom pop stars such as
Clairo and
Beabadoobee" and that it "captures all the brilliance of Lacy's outstanding second record
Gemini Rights".
Consequences Paolo Ragusa described the song as "a miraculously good pop song", "a testament to Lacy's creative freedom", and "one of the most deserved breakthroughs of 2022", which "twist[ed] the concept of desire and a missed connection into something wholly original and authentic". Paul Tingen of
Sound on Sound wrote that the song "lacks the typical trappings of modern hit songs" such as
808s and
Auto-Tune, but that its attitude was the likely reason for its popularity. For the
Washington Post, Chris Kelly described "Bad Habit" as "a gentle pop earworm that sounds like staring at stars glued to a bedroom ceiling".
