Readability and if you use the `it { should <matcher> }` syntax, then the `<matcher>` supplies the description of the example so you don't have to do

```ruby
it 'is false' do
  expect(creation.exploited?).to be_false
end
```

which would repeat the word 'false' twice unnecessarily.  Additionally since this is a `?`, Boolean method I could have done `creation.should be_exploited` as `be_*` will work with an `?` method, but that form would cloud that this context is about testing the `exploited?` method and not the `creation`.
