The little villagers who inhabit Isola definitely have minds of their own, and they don't always seem as concerned about their situation as you are! Curiosity seems to be a genetic trait of these little people!
The game is designed so that the food supply is a little tight at the beginning, however there are some things you can do to improve the situation. In v1.0 of Village Sim, due to a difference in villager productivity between when the game is not running and when it is, you can improve your food and research point situation by leaving the game running at slow speed with your Palm on AC power. Not everyone can do that, however, since they use their Palms for more than playing games.

If you're able to do that for even half a day (or, best case, overnight), you'll see a significant increase in the food supply, research points, and any building projects that may be going on.
Another thing that works to improve your research point production (albeit a boring thing to do) is to repeatedly drag your villagers back to the table as they start to move away. This does two things: 1) increases their skill, which in turn increases the quantity of points they produce, and 2) keeps them from spending time in "unproductive" pursuits!
