When there are many people that can do the work, then we all tend to leave the work to someone else.

And we see these effects really increasing very rapidly with the size of the team.

So there will be less social loafing in a team of two people and much more when it's a team of 10.

We know that since basically Wengelmann, a French engineer, ran some studies with men pulling a rope at the beginning of the

20th century, as you can imagine, when several men pull a rope together, they invest less effort than when they do it by themselves.

And we see it in studies all the time.

The simplest solution, make sure that you can identify people's contributions, that it's not one pile of contribution.

We know how much each person did.

We can say that, Whitney, this is how much you did, and Ayala, this is how much you did.

We even see this with a donation.

So, you know, sometimes you give money to charity and it all goes into some like large bucket and your $10 contribution feels like a drop in the ocean.

Other times, some organizations and charity campaigns, they make sure that they list each donation.

So you can see that Whitney gave $10 and this is much more

more motivating and likely takes care of the problem with having a large group of people working together toward the goal.

I would say that yes, do goals are better than do not goals.

Approach goals are better than avoidance goals.

What do I mean by that?

When you invite people to bring more positive thoughts to their lives, this is much easier than when you tell them not to think about something negative.

They push away negative thoughts.

When you invite people to bring more healthy foods to their diet, that's easier than removing foods from their diet.
