Jeg legger ut en artikkel av Michel MASSON i EASA. Artikkelen omhandler Capture Errors, noe som er aktuelt for alle oss som flyr, men også innen andre yrker. Det handler om bevissthet.

God lesning😊

The 5th or the 6th floor?
Last week, I moved from the 5th to the 6th floor of the EASA building, as I am now part of the EASA Communication and Safety Promotion Department, headed by Janet Northcote.
Friday morning, in the elevator – guess what – I pressed the 5th floor button instead of the 6th, a classical mistake.
This error qualifies as a routine error because the 5th floor button was previously commonly used. It could also be considered a capture error – a less commonly used term—since my finger was kind of automatically attracted or captured by the 5th floor button, despite it being inappropriate in this new context, and I couldn't suppress the action.
A moment later, I noticed the mistake and corrected it. The lift control panel then looked like what you see in the picture, with both the 5th and 6th floors selected:

The error was mainly due to habit, combined with poor attention management – my thoughts were elsewhere, focused on my afterrnoon’s tasks. The side-by-side placement of the two buttons – the design element, didn’t help either.
The consequences of undetected or uncorrected errors depend on the system, the situation and the environment: they can range from none, to minor, serious, or even catastrophic.
In this case, the error had no real consequences – except it gave me the idea to write this short article.
Capture error
Would you Google “capture error”, the AI Overview provided by Google (*) would provide the following definition, examples, and mitigation measures (ref. July 25, 2025):

Definition
A capture error is a type of human error where a more practiced or frequently performed action is mistakenly executed instead of a less familiar or intended action. This often happens when two actions are similar, and the more ingrained one "captures" the behavior.
Examples of Capture Errors
Phone Numbers:
Intending to give your work phone number but accidentally giving your home phone number.
Typing:
Typing your name when you meant to type another word that starts with the same letters.
Driving:
Driving to your old workplace instead of your current one, even though you've driven to the new one many times.
Computer Input:
Typing a word you frequently use when you meant to type a different word with similar first few letters.
Capture errors are considered a type of "slip": a type of error that occurs when a person's actions don't align with their intended outcome, often due to automaticity or a lack of attention.
How to Address Capture Errors
Awareness:
Recognizing that capture errors can happen can help people be more mindful of their actions.
Redesign:
Interfaces and processes can be redesigned to reduce the likelihood of capture errors by making the intended action more distinct or less prone to confusion.
Training:
Targeted training and practice can help reinforce the correct actions, making them less susceptible to being captured by more automatic behaviors.
