Your sample sizes are small, your standard deviations are high, your conclusion means nothing, and you should feel bad!

yes, she did state a hypothesis. If you were a member on her official website you would know this.

I could not agree more. She failed to first state a hypothesis and completely neglected uncertainties due to random and systematic error.

This video is bullshit.. how can you weigh a cock by lifting the scale, in the frame of the cock, there will be a pseudo force pushing it upwards, therefore, the weight of the cock must be less than that... Stupid pornstar.. did not go to college

the scale has to be subject in some damned way. The weight will be correct if the scale is not moving. Or are you waiting for the balance to be floating? She has to do strength up just to counteract the weight, just as if it were on the fucking table.

Honestly, I don't get why por stars even try to do math, as it's all scripted. I second what 'theprofapper27' said. Also, Why are you wearing the hijab? You are Christian. Goddamn. I don't understand why this is quality porn. Wow.

Smh a good scientist would have at least 100 men for a credible experiment. I'm disappointed Mia. I thought u were smarter than that.

This isn't science. I'd hoped for more from you. But I expected as much.
