I agree with both! We have great mesorah from Gemora that we should use sevorah to make decisions. Sometimes, you can experiment yourself, others – consult experts. In all cases, you need to be critical of what experts are saying and strive for truth. Of course, one should listen to gedolim here – who know halocha and either studied science themselves or can consult sufficient authorities.
