Not likely.

Don't do this. How do you think it will help? Do you have untrusted 
local shell users? If so, you are doomed anyway. They will find an 
opening, get root, and get out as they wish. If it's just you on the 
machine, OUTPUT filtering is silly. Use self-control, not netfilter.

iptables -P OUTPUT ACCEPT

For the return packets, go stateful. An example is posted in the thread 
earlier today, Subject: help me. It's also given and explained in the 
Packet Filtering HOWTO.
