Since the data was just anecdotes, how did you determine that you were at the low end, compared to what parent comment pointed out - that people self report high?

I disagree with the parent comment's assumption that such data would necessarily be inaccurate. I found it to be quite accurate. I know that I and most of my immediate peers entered our salary data into the spreadsheet, and all of us did so accurately. There were detailed instructions telling you which internal website to go to to find out your compensation information, and the instructions said which values from that to fill into the spreadsheet.

Can you share the methodology of your study where you determined the data to be accurate?

> It's anonymous. I'm not sure why you think it'd be so susceptible to bragging or complaining.

Because people are irrational by their nature, and it takes a lot of effort to eliminate such factors when you make a decision.

I've pointed out some huge issues with the anonimity of this site in another comment.

But apart from that, if a site has no privacy policy, you should have no expectation of privacy or anonimity. If they added an advertising tracking tag they could easily match the data you provide to your real name, your hobbies, your online shopping habits, your marital status...

Maybe fill it out via Tor, and fuzz the postal code.

That means you were 'bought' into thinking it was a good idea by a mere $10,000. Maybe you should have actually been paid $30k more all along - and still.
