“If a journal publishes a result, they are ethically obligated to publish further work that refutes that result.”

Too general. Few in science would accept this. The claim here is the weaker one that journals are ethically obliged to accept failed replication studies - and even that is non-obvious to me. (Should Science also be obliged to accept _successful_ replications? No? So it should accept papers on the basis solely of the results? Hello, publication bias.)
