We are all already within a spreadsheet
Nobody ever told me there were hidden columns in the spreadsheet. Once I begun spending more time outside of my comfort zone, beyond where all spreadsheets were the same, and started looking over the shoulder of my partners spreadsheet, and other friends, I started noticing they had different columns, or entirely different spreadsheets. I had never noticed the male harassment column until I started watching my partners spreadsheet on a regular basis. I never really considered the calculations she had to make walking home from the bar after a conference, or how she would receive entirely different responses for exact same criticism about technology. I could say something and nobody would feel the need to tell me I was wrong, but if she said the same thing, 20 dudes would come out of the woodwork to let her know how out of line she was. She had a bunch of columns in her spreadsheet that I had never seen before.
