The Cardinal Sin of Redundant Boolean Checks

Description

A three-panel meme captioned 'newbie programmer be like:'. The first two panels use the 'Drake Hotline Bling' format. In the top panel, Drake looks away in disapproval from a simple, clean line of code: 'return someBool;'. In the middle panel, Drake smiles approvingly at a much more verbose and convoluted block of code that accomplishes the exact same thing: 'if(someBool==true&&someBool!=false){ return true; } else if(someBool==false&&someBool!=true){ return false; }'. The third panel, the punchline, shows Drake being escorted away by a police officer, implying that writing such unnecessarily complex code is a criminal offense against programming principles. The meme satirizes a common mistake made by beginner programmers who haven't yet grasped concise boolean logic, often explicitly checking for true/false conditions when the variable itself is already a boolean. For senior developers, this is a painfully familiar anti-pattern seen in code reviews, and the final panel is a humorous exaggeration of their desire for code quality enforcement

    The junior’s PR turned “return flag;” into a 12-line if/else because “defensive coding.” I told him the only thing that code defends against is the CPU’s branch predictor having a quiet evening

    This is the same code pattern I've seen in production after a 6-month enterprise consulting engagement that billed $2M to "ensure robust boolean validation across all service boundaries."

    Ah yes, the classic junior move: checking if a boolean is simultaneously true AND false - Schrödinger's variable, where the code exists in a superposition of 'will never execute' and 'why did this pass code review?' The real kicker is that even if you removed the impossible logic, you'd still be left with 'if(someBool==true) return true; else return false;' - which is just 'return someBool;' with extra steps and a desperate cry for mentorship

    Turning “return b;” into “if (b == true && b != false) …” is SAT-solver cosplay - leave three-valued logic to the legacy DB; in a language with booleans, just return the bit

    If your boolean needs both == true and != false, you’re auditioning for a SAT solver - return someBool and let the linter retire in peace

    Because trusting a boolean's self-awareness is for senior devs; newbies need if-else therapy to confirm true isn't lying
