Week 7: Security theatre, at door scale

The gap between hardware that provides security and hardware that only performs it

12 April 2027

A deadbolt and a chain lock look like they belong to the same category of object. One resists a shoulder; the other resists almost nothing, and mostly exists so the person behind the door feels like they checked. Doors are full of hardware like this — heavy-looking hinges on the unlocked side, a keypad next to a door that’s propped open all day, a push bar that announces “alarm will sound” and hasn’t been wired to anything in years. None of it is lying, exactly. It’s performing a promise the actual mechanism doesn’t keep.

This matters for a redesign for the same reason accessibility does: a fix that looks more secure without being more secure has fooled precisely the person who trusted it most. The proposal due next week asks you to hold both lenses on the same door — does it work for someone who isn’t you, and does it tell the truth about what it actually does.

• security theatre: hardware that performs a promise it doesn’t keep
• reading a lock or closer for what it actually resists, not what it implies
• signage that asserts a rule with nothing behind it
• holding this lens and week 5’s access lens on one proposal at once
