Я хочу иметь возможность вызывать соответствующую информацию, сопоставленную с компонентом, как показано ниже 

class ResultsLists extends React.Component {
  constructor(props) {
    super(props)

    this.state = {
      results: resultsData
    }
  }

  render() {
    const results = this.state.results.results.map((result) =>
      <li>{result}</li>
    );

    return (
      <div className="rst-List">
        <ul className="rst-List_Items">
          {results}
        </ul>
      </div>
    )
  }
}

Я не могу заставить его работать, и я получаю ошибку - объекты недопустимы как дочерний элемент React. Кажется, есть разные причины того, почему это не работает, интересно, может ли кто-нибудь проверить работоспособность.

Вы отображаете на results, но затем вы помещаете весь объект result в JSX.

Это пример того, как отобразить данные: 

const someData = [{ name: "Colin" }, { name: "Ricardo" }];

const App = () => {
  const temp = someData.map(o => <li>{o.name}</li>);

  return (
    <div>
      <ul>{temp}</ul>
    </div>
  );
};

Обратите внимание, что у нас есть {o.name}, а не просто {o}.

Рабочий пример здесь .

Так что в вашем случае вам нужно что-то вроде: 

const results = this.state.results.results.map((result) =>
  <li>{result.title}</li>
);
...
