[ most variables have the same variable names as study 1 and 2 ]
experiment_number = the wave/experiment ID (from referrer) that the participant was run in. The present research was run together with several other studies.
serial = participant unique serial ID (from referrer)
path = the order participant complete the surveys in
	This specifies their condition:
	1: Offset Frame, list pro expensive ticket thoughts first
	2: Tax Frame, list pro expensive ticket thoughts first
	3: Offset Frame, list pro cheaper ticket thoughts first
	4: Tax Frame, list pro cheaper ticket thoughts first
begin_time = date and time that participant began the study (including the other, unrelated parts of the wave, which occurred before and/or after)
duration_mins
confusion = if there were any confusion
confusion_yes = if answered yes for confusion question
comments = if there were any comments
comments_yes = if answered yes for comments question
overall_duration = overall how long did the survey take
additional_comments = if there were any other comments on the study
end_time
tax0off1 = Offset or Tax frame (tax frame = 0, offset frame = 1)
product_offtax = whether participant chose offset/tax on the ticket product
	•	1 = choose the tax/offset option
	•	0 = choose the cheaper option
product_strength = preference strength for their choice of offset/tax option on the ticket product
product_mandatory = support for making the carbon tax/offset option mandatory

expfirst = the experiment (id) being presented first
expsecond = the experiment (id) being presented second
whenfirst = time the participant finish the first experiment
whensecond = time the participant finish the second experiment
-----------------------------------------------------------------------------
numfirst = number of thoughts listed after the first prompt
numsecond = number of thoughts listed after the second prompt
totalnum = total number of thoughts listed
numpro = number of thoughts listed favouring the more expensive (tax/offset) option
numcon = number of thoughts listed favouring the more cheaper option
numdif = numpro - numcon

experiment_id = the experiment ID (from referrer) that the participant was run in. The present research was run together with several other studies.

followedprodir = proportion of thoughts correctly supporting the more expensive ticket when asked
followedcondir = proportion of thoughts correctly supporting the cheaper ticket when asked
followedalldir = proportion of thoughts correctly supporting one or the other as appropriate
NaturalElke = 1 is natural order (as outlined in the paper intro), 0 is unnatural order 
NaturalDave = 1 means listed thoughts about the expensive ticket first, 0 means listed thoughts about the expensive ticket second
followeddir1 = recoding of the followedprodir variable into a dichotomous variable, by always rounding up (so if someone correctly listed at least one pro thought when asked, that counts as following directions)
directionsbias = followedpro - followedcon
