Normally, I might be suspicious of such a paper because the measurement sounds kind of farfetched. Some of my friends in aggression research scoffed at the research, calling bullshit. But I felt I could trust the research.
Why? The first author has published null results before.
I cannot stress enough how much an author's published null results encourages my trust of a published significant result. With some authors, the moment you read the methods section, you know what the results section will say. There is rarely any real threat of falsification. Every paper supports the lab's theory, and one is left wondering whether there are null results hiding in the wings.

You could think of this like sticking pins into a Voodoo doll."
In the case of the voodoo doll paper, the first author is Randy McCarthy. Years ago, I became aware of Dr. McCarthy when he carefully tried to replicate the finding that heat-related word primes influence hostile perceptions (DeWall & Bushman, 2009) and reported null results (McCarthy, 2014).
The voodoo doll paper from McCarthy and colleagues is also a replication attempt of sorts. The measure was first presented by DeWall et al. (2013); McCarthy et al. perform conceptual replications testing the measure's validity. On the whole, the replication and extension is quite enthusiastic about the measure. And that means all the more to me given my hunch that McCarthy started this project by saying "I'm not sure I trust this voodoo doll task..."
Similar commendable frankness can be seen in work from Michael McCullough's lab. In 2012, McCullough et al. reported that religious thoughts influence male's stereotypically-male behavior. Iin 2014, one of McCullough's grad students published that she couldn't replicate the 2012 result (Hone & McCullough, 2014).
A researcher that publishes a null now and again is a researcher I trust to call the results as they are.
