Haha, uhh no.
Would be nifty is it were accurate, but no I don't think so. There are too many lines which represent to many things, and resultantly palm readers can never be 100% accurate. Then if one thing does match, like you become rich 'cos you money line says you will- they think it's warranted enough to believe in the technique. However, in reality it's coincidence.
I would love to know what the scientific studies were? For the life of me I just don't know how you could accurately measure something like that. If you just chose a bunch of people and checked how many reading were plausible, you can fudge it. If someone wants to find a link, they will (like star signs), since the science to it in my opinion is just so ambiguous.
But then, I had a bad reading from a quack once. That is probably the reason for any negativity. After all, I love star signs
